Too much nitrogen. Riding toxicity, leaves dark green, clawing down. Looks like nute burn on your tips. Your gassing it too much. Heat don't look like it caused a issue yet.

Yellowing leaves.
Yooo! I have a few lower leaves starting to yellow I’m pretty sure its because the plant has switched all the energy to bud production so my question is, is it ok to defoliate the yellowing leaves at this point?

Light colored sugar leaves
I'm at the end of week 6 and the plant is looking healthy overall but there are some bud sites that have some sugar leaves that are developing with a lime green color. Im thinking I might have been a little high on the ec so I backed off a couple days ago. Thoughts?

Leave's tips color turning yellow
Ciao a tutti, da 2 giorni ho notato che le punte delle foglie si stanno ingiallendo. Ho pensato di allontanare la luce dalle ragazze, nonostante stia usando una LED (marshydro ts1000). Sapreste dirmi cosa sbaglio? Dovrei agire anche sulla quantità di nutrienti?

What is this leaf showing?
Anybody knows what is going on with this plant? My first guess was nitrogen toxicity because of the leaves clawing down a week ago, but I am not fully sure anymore with how the leaves are looking now.

Name the deficiency.
Problem is mainly occurring on leaves near the top, but not the newest growth. Initially are less green, then start to yellow followed with brown spots. The oldest leaves near the bottom are seeing some effects, but as acute as the mid-upper leaves. Curl likely due to warm temp

Yellowing sugar leaves!!
Hiya Folks 🌞 I've started to notice some of the tops have developed some yellowing on the sugar leaves tips and edges and I'm just wondering why this may be? Luckily she's nearing the finish line so I'm hopeful it's not too much of a problem?

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?
