My friend has just finished his second week of flowering in a vertical system that looks like this one -> ( http://www.hydroshop.ca/english/ecosystem-vertical-growing-system.html ) . He is using grodan v-slabs made of rockwool. He seems to have a major ph problem now ! Even if he changes his reservoir with fresh new solution, his PH drops by 1.2 points within the first 24 hours !!!!!!!!! He starts if off at 6.2 and everytime the water goes through his slabs it comes back .2- .3...
Why does the ph drop from 6.2 to 4.9 with in a day !?!?
