Cane grows weed

At the beginning of the week I started to notice discoloration in-between the veins. I figure that the humidity being too low is causing issues with magnesium uptake. I've upped the humidity from 50% -> 65%. The plants responded well. Ec is now up to 1.0. Ive added molasses and silica to my feed. They're going to be added once a week. My main source of nutrients comes from Floraflex V1 and Floraflex V2 Day 19 I pruned some leaves and did some slight LST to allow more light to reach the important branches of double grape. Ill do the same to toof decay once its bigger. Day 20 I pruned leaves from both double grape and toof decay. Im disappointed in the size of toof decay. The bean itself must've been a weak one. I didnt do anything to stunt it. Day 21 I pruned more leaves from double grape.
