Robertsanswered grow question 3 years ago My question is what is your water level at. Should be at tips of roots only. Also are you adding any hydrogen peroxide to your solution, I add 1 ml to 5 gallons. Helps keep root rot away. My plant looked just like this when I had root rot start on my pineapple express auto like week 3. I saved it right then but can look for similar visual issues to yours. I think you got the same issue I had going on personally. Root pictures would help as well in diagnosis. Good luck and ph about 5.8 in vegging, and 6.2 to 6.3 in flowering is best ph ranges. Good luck and happy growing 🌱
