Click here for more images: http://imgur.com/a/ruF0s#KDM8b Just wondering if any of you fellow growers can help me out with a quick diagnosis? She's at week 3 and was flushed through a week and a half ago (just to clear any salt buildup). Only had 1 feeding since flower at very low concentration with a pH of 6.4 - 6.7. It seems to affect the middle/top of the plant. It started going like this a few days after it was watered with just RO water. It began off as a whiteish colour making me think it was too close to the light - I had a 600 about 8-9 inches away, so I moved it higher. Temps & RH are good and stable. They were transplanted from coco into compost & perlite, and are in 17L pots/ 4.5 gallons Problems getting worse but im not sure whether its pH problem, deficiency or what! Any other information you need to help diagnose? Lemme know!
