Can someone identify this DEF??

started grow question 6y ago
It is almost time for harvest, is this normal or a bad DEF? It’s the worst I’ve seen on my plant so far.

Looks like potassium Def, anyway if you plan to harvest that's a good thing it seems your plant is eating up all the nutes and if you plan to do a final flush it will go fine for sure. Good harvest

Let it grow or cut it out?
One of the seedlings isn't doing so hot. Should I just start a new seedling in it's place or give it more time? I've had a stunted seedling like this before in a previous grow and it ended up yielding a lot...

Is this turning purple from temp change
So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

Leaves turning yellow
Old leaves die,mig-age turn light green,new stay green.Is this normal for just week 4 of flowering on my auto? Do you think it might be ready sooner than week 11? Or is it just a problem? "feeding/watering every 4 days,never used cal/mag supply,medium=soil light" Thanks growers

Leaves down
Hello,fellow growers. My Royal cheese 🧀 seems to be doing not so well in her second week. Leaves are turning yellow and down. Can this be because of overwatering ? I gave her two litters of water two days earlier and now it's all sad. Please help me out.

What could be causing this?
I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far. I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout. Anything else it could be??
