Looks like Heat and overwatering + calcium deficiency possibly caused by Potassium excess.

Dry yellow/brown tips, starting from the oldest leaves
What's wrong with the plant this week? Many leaves have dry yellow/brown tips, starting from the oldest leaves. Is it some kind of nutrient deficiency, and how do I fix it? I tested the pH of the drainage water and it was 6.8, I've flushed it down to 6.2 now.

Leaves turning slightly yellow
Hi guys, I have a problem that I need some advice with. I have some slight yellowing of the leaves, it’s not happening at the top of the plant. I have tried flushing the plant, and haven’t added any fertilizer since the yellowing. My light is 12” from the plant.

Light green tops
I've got one plant with extra light green tops. Any suggestions or is this normal sometimes? See my diary for feeding details. I've treated all plants exactly the same the only difference would be the type of pot (airpot) and I didn't root prune like I did the others.

Hello all, I am having some issues with my outdoor grow. It seems the leaves are beginning to turn yellow. It has not received nutrients I’d say in about a month. The main reason for asking is because I do not want to over correct by adding nutrients if that may not be an issue.

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Yellow dots on the leaves
Hi guys I need your opinion I noticed some yellow dots on some leaves of my plants and I wanted to know if it can be caused by too much light or too much nutrient Or maybe it's just normal and I'm just paranoid XD I circled the dots that I'm talking about

Brown spots, PH in run-off is in the high end (6.5~)
I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?
