What? Do Not listen to these people on here. I could see what's going on within 5 seconds. It was to much light, to much light doesn't allow the plant to photosynthesis nor transpire which causes water to sit in the veins of the leaves which is why you have speed bump leaves and squinched internodal veins. Water went back down the plant and rooted the root hairs which prevented his from uptaking nutrients which is why you have deficiencies. You raised the lights and it gets better over time but it takes to long to recover, well over 30 days to recover and the leaves damaged can never be fixed again, you have to wait for all mew growth extending your veg another 60 days which is why you have to throw it away. Don't you have a par meter? Are you still raising and lowering lights based on mfg recommendations? If so, no wonder your killing your plants. The fact everybody said it was Ph shows nobody knows anything about Agricultural anatomy which is why it takes several years of College to know what your doing and plant anatomy. Had you had asked a Biosystems or agriculture engineer soon as it happened you would have had a answer right away and you wouldn't have got advice from failed growers.
