Morpheus

Dwc can be a pretty temperamental way to grow. The water has to be kept cool and pH is hard to maintain. General hydroponics maxi nutrients are the most stable nutrients I have found. I really think you have a combination of light burn and pH issues on her. I use ladybugs to deal with pests. They clean out aphids and mites pretty fast. Hope you can get it turned around. Good luck!

hey there morpheus , hope I answered your question you have classic magnesium deficiency symptoms , your healthy plant probably just stretched too fast for its own good. Anything else you need just let me know ! 👊

You are using a lot of magnesium and I don't see any calcium in your feed schedule. Magnesium will lockout calcium if you use too much. Calcium helps deal with heat stress. I would say light burn. This is a great reference with some pics that look like your plant. Good luck and happy growing!🍀💪 https://www.growweedeasy.com/cannabis-light-burn

Thanks for the responses :) Have now added 5ml of calmag (10l reservoir). Giving it an hour to mix, then I'll rebuffer the pH. Fingers crossed!

Adding to my question: pH was 5.6 on Saturday when I first mixed the nutes), and then with the air stone has come up to 6.5 or so. I've added a small amount of pH down to temper this back down. For Magnesium, I'm using floraBloom (3% magnesium). Light is now approx 1m above the plants,... So I don't think it's pH, mag deficiency or light burn. Any ideas?

At what point did you top her? Seems like week 2?

@Mr_Weeds_Autos, Thanks! Actually experiencing what appears to be a brown algae bloom,w which is a pain. Probably a result of sprouting in a transparent glass jar. hufff. Everything now in a blacked out bucket with a black lightproof cloth over it, and adding bennies daily. Fingers crossed as the bloom has caused the pH to skyrocket (8+). Moved from my usual organic lemon to a more potent commercial pH down
