overnight yellow leaves with brown spots
jamjam887766started grow question 5y ago
These leaves (about halfway up on #1) turned yellow with brown spots overnight. I didn't check the soil before giving it nutrients two nights ago so I was wondering if it has to do with overfeeding. The soil is damp and kinda packed together. Any idea what's going on?

Judging by the amount of nutes you are giving, the fact that I see no pH or EC / PPM info, I would think you have a mild case nute burn. Since you are already past 8 weeks, I would stop all feeding and give it plain water and let the plant consume what's left on the soil.

this looks like a nitrogen lockout caused by your pH being incorrect

If you recently added a booster, I think that's the problem. Too much P will lockout calmag. Check your runoff and flush if necessary.

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??

Brown and yellow leaves help me get my plant healthy plzMy first time growing and my clone has started to get these brown dots everywhere. Now some of the leaves are dying and it’s getting worse. Online it says it could be mildew or a calcium deficiency.

Roots getting brownMy Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!

Seedlings with yellowing leaf edgesAny insight on what may be causing the yellow edges on these seedlings?
I'm reusing FF Ocean Forest that I used on my last grow. I didn't amend the soil in these containers as I didn't expect they'd need anything before it was time to transplant. pH was good at last harvest.

Yellow leaves on plantMy tallest plant has been displaying signs of deficiencies/abundances of nutrients. I am worried about the yellowing leaves that have been getting progressively more pale for the last week. Is this a light, ph or nutrient issue? Week 6 of flower right now and N has been cut down.
