pH Crashes and EC Spikes in DWC - is this the issue?

Noob, but studying hard. ISSUE: A couple days before the flip my pH started crashing from about 6 down to 4 (sometimes lower) in about 12 hours. EC/PPM would spike in same time period. RIG: small (5 gal) DWC with top down and two air stones (air pump is outside the grow tent), Humboldt Seed Co. Magic Melon and Collie Man Kush (two of each) sharing same res, RO water and (prior to these issues) changing res about every 7-10 days. Lotus Nutrients (currently Bloom and Boost).

Strange pH problem in flowering stage, changing to tap water from RO

Hi all My first grow ever, I have a 9 week old autoflower in DWC in its flowering stage and I have been using RO water with added Calmag and Flora Trio nutrients its whole life (around 1/3 of the recommended dosage), no issues. Around 2 weeks ago I started getting sudden pH drops, it would go from 6.2 to 4.8 every 24 hours, yet the plant was growing nicely still. I ruled out Pythium and Algae, I did a res change twice and adjusted nutrients to no avail, the pH kept dropping, whilst still...

Using too much Hydroguard or Southern AG bad?

Normally I dilute Southern AG down to 1:20 water ratio then use 1ml per 4L. However, I read you can't add too much beneficial bacteria so I added 10x of my usual amount.

High Voltage Aeroponics

Hi guys, for the last couple of years, I've been playing with high-voltage electric fields to make the droplets within an Aeroponic system negatively charged and attracted to the root's of plants. It's come on quite nicely and found I was able to affect the surface tension of the nutrient solution upon formation of the droplet so that I also have much more control of droplet size/dispersion with the root zone. I was hoping to get some feedback in regards to the potential features and the... High Voltage Aeroponics from Hydroponics / Aeroponics https://www.rollitup.org/t/high-voltage-aeroponics.1025729/

I'll be one hundred with those of you that are reading this, I didn't order seeds from royal queen or some other high quality seed seller. Nor did I breed seeds from a strain into a special hybrid that'll cost its weight in cocaine. My seeds are straight out the hood from a corner d-boy who had what we call some "loud", I'm for positive that you've at least heard of it.

DWC PPM question transition and flowering

I have purple punch and strawnana dwc 10 or 12 gal bins with usually 4.5gal of solution in them and two large air stones. They are in 5" netpots. I am using the GH flora series and RO water that introduces call and mag back into the water. The RO system was for hydroponic growing.

To use reverse osmosis or to not?

So as stated, I’m just curious how many people use reverse osmosis systems to draw water for their grow. I bought one when my ppm are only 160 out the tap, an now I’m debating on the purpose of if I should even use one. So I’m wondering how many people use tap water and who uses reverse osmosis and why?

Flood and drain, air stones waste of time?

Hi guys, I am running flood and drain with 100L (26 gallon) reseviors. I have airstones in all my reseviors. But reading up recently there is a lot of debate about wether this is a good idea (introduces airborne pathogrens and other nasties). Should I stop doing this? Is a move to small recirculating pumps the best alternative? Do I even need to worry? Will the constant flooding and drain be enough to keep the reseviors well mixed and airated?

Added molasses to my hempy buckets. Not good

I read an article where molasses was recommended for hydro. Everywhere else I read said don't. I thought what the hell. The general hydroponics flora nectar @ $60/gallon is very expensive. $17.92 for a gallon of high brix molasses seemed like a steal of a deal. Let me first say the plants did not suffer any harm from the molasses. However, if I had not discontinued after 2 weeks of application I would be telling a different story.

Question about rockwool

My last grow I used 6x6x6 inch rockwool cubes for a heavy sativa grow, and was getting so much root growth from the bottom. Is this normal, or bad? Should I go for the 8x8x8 inch rock wool cubes this time? My only concern with those are that the hole doesn’t come precut.

So I feel as if I've done fairly well in soil and sure have learned a lot on my first grow (I'll post a pic also). I'm really considering hydroponics, but a bit overwhelmed by all the choices. What system do you use and why? How's the maintenance? What necessary or unnecessary things have you found to go with it? Any advice you wish you would have known or product suggestions will be greatly appreciated. I have a 5 x 5 gorilla shorty grow tent (with the extension on its 68...

Update on first grow

So out of four plants I got 3 females out of bag seeds. Its my first grow and i wanted to learn how the plants naturally grow so i topped one and let the other two grow naturally. Im running into a problem with one of my girls in flower. She wont stop growing! She has grown taller than my light and i cant move it up anymore! I tried to see how much bend she had to maybe tie her down but the main cola bent and i had to fix it. Shes still doing good and healthy but i was wondering if it will...

Different NPK ratio for different stages of flowering

Hi everyone, i would like to ask a question to the top growers here, but also share opinions about our experience: which NPK ratio do you think works the best for each phase of flowering? Meaning transition and stretch, then early budding, bud swelling, and ripening before an eventual flush? And most importantly, how do you find the right proportion between phosphorus and potassium in the different stages? A lot of growers and nutrient companies suggest higher P than K, other growers claim...

Reservoir question?

Hello so I built my own RDWC this is my second build, for some reason I have to keep filling my reservoir every two to three days I was wondering if there is a way to add more water to reservoir without it going to the rest of my buckets and killing my plants and flooding my system? from Hydroponics / Aeroponics https://www.rollitup.org/t/reservoir-question.1023526/

Any Suggestions for inline filters for and aero system?

I have a 50 micron filter at the intake and a 200 mesh spin down filter inline. I was wondering if anyone could recommend a small easily cleanable inline filter that I could splice in after the spin-down filter and before the pump? By the way the Aqua Tec pumps I bought are great. I could not believe the time their tech advisor spent on the phone with me, they have literally hundreds of combinations of options, and Bill did a great job spec ing my pumps out.

I'm looking to go hydro. Was going to build a diy waterfall system using 17gal totes for bloom and 5gal pots for veg, e.g. 2 separate systems in 2 separate tents, 6-8 spots per tent. I was offered a nib super Closet 24 site bubble flow system in 6.6gal pots for a good deal which is basically 2 standalone 12 site systems with 2 air pumps, 2 reservoirs and two water pumps; just not sure how good the system operates since lines seem small and buckets are smaller.

Same EVERYTHING and one of the two is having a Droopy time :(

Aloha, So I started some seeds I had on hand, (I didn't have much faith in the genetics) and these are the two females out of 6 I started. I had to pull the males out of the system once I identified them. But the roots were already so tangled I just got what I could easily and left the rest to rot, hoping the extra enzymes I added would help break them down. Both of these simple DWC systems have had identical treatment and there were males pulled from both, so both had dead roots but...

First aero start-up

Been growing since 67, but this is the first time I tried it without soil. Didn't need to grow inside until now. Real led light due in a week. Been moving my spyder by hand about six times a day.

Seeds in buds

I’m almost in my 6th week of flower and I started noticing seeds in some of the buds . It’s only a few plants. I check the plants everyday I have seen no bananas or pollen sacs. Any help of why this is happening would be great. Could outside air have pollinated them? Or some other outside source?

RDWC Questions

I'm finalizing my design for a RDWC run, and have some basic questions that may or may not influence my end build. 1) Does it mater how high up you place PVC on buckets? Can it be roughly half way up the bucket, or is lower better/necessary? 2) I was wanting to place the control bucket outside my tent, but the ports on the tent are higher than the level I plan to have the return lines on the buckets.

Anyone Have Problems with Hygrozyme?

Long story short, I ran out of Hydroguard by GH that I have used for years in my hydro reservoirs. Stopped in a hydro store to get some and told that it is discontinued and that Aqua-Shield or something is gong to replace it. So the hydro owner told me to use Hygrozyme instead of the GH products at 3x the cost. Anyway I changed out the various res on my 48 plants in different stages of clone, veg & flower and ended up with slimy brown roots and a nute lockout. I have since flushed with...

Germination of seeds - ready for r/dwc

Hey all! I thought I'd share an experiment about achieving from seeds to R/DWC directly. First, sprout the seed in paper towel... Should take ~48 hours, then fill your netpot with clays. Take the little one with squeezers and place it gently, leaving the shell's side in an upside position, between two pebbles, to make it easier for the head to grow and reach for the light.... Just soak your netpot every few hours to keep things moist... The root system will establish itself and you'll see...

GH FloraBloom DIY EXACT

Okay.... I finally got it right!!! I was able to figure out that GH FloraBloom most probably doesn't contain 1.5% Magnesium because the only water soluble source of Magnesium that is suitable for hydroponics is derived from Magnesium Sulfate. You can check that fact on Wikipedias solubility chart. Magnesium Sulfate Heptahydrate (Epsom salt) or just plain old Magnesium Sulfate will always be heavier with Sulfur than Magnesium. A 4:3 ratio approximately. So, when you make a mix containing 1.5%... GH FloraBloom DIY EXACT from Hydroponics / Aeroponics https://www.rollitup.org/t/gh-florabloom-diy-exact.528636/

Not as much bud growth as I hoped at this point but I have over 30 colas that will get more than 1/4 oz off of each so for one plant so should be able to get over 1/2lb off one plant maybe up to 12 oz. 5 1/2 weeks of veg before I flipped her. What she has lacked in explosive bud growth she has made up for in being frosty. She had insane stretch after the flip so strong on the sativa portion of the strain.
