Can you post up any larger photos into the post? How far along are the plants? The entire leaf looks very yellow and dry from what I can tell. Do other leaves have the tips browned, but otherwise green? Generally a sign of gentle nute burn is still a healthy green all around, but many tips will be yellowed, curled, or browned all together.
if you are talking about the one yellow leaf then I wouldnt worry about it. If you are seeing brown tips on all of the leaves then you might have nutrient burn.
It’s a 3ft plant and it’s effecting the lower middle canopy. It started after I gave them some nute water. It started Turing yellow at the base and slowly took over the leaf in about a 24hr span. Once they turn fully yellow even if not dryer out they fall off and it’s weird because they feel perfectly healthy and not wilted Sent from my iPhone using Grasscity Forum
Some more pictures would really help. It seems strange that the leaves would turn fully yellow within a day, that's pretty quick.
Replaced my avatar pic. That’s my other plant and what it started to look like the other day Sent from my iPhone using Grasscity Forum
Found out what happened. I guess my ph changed over time but I had it in sealed container and wasn’t expecting that. Leaning new stuff all the time... Sent from my iPhone using Grasscity Forum
