That's light stress for sure you can tell by the top of the buds too. Just raise the light. 👍🌱

Dark green leaves in meringue
Is my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?

Any suggestions on what you think the problem could be with #2 could be welcomed. Air pots, soil dries out 2-3 days, temps stay in same range, since sick no training was done, brown spots starting at old growth and moves up plant on big fan leaves 1st then rusty look as progress?

Ugly leaves
So, guys.. I asked a question here, like 3 days ago, about some leaves. I think I have found out what has happened. Mold ignition, but very few, at the root. Have already medicated. Do you think this is a mold symtomn? Cheers!

Possible P Deficiency?
Hey everyone, hope all is well. I noticed these past few days some dark spots appearing on some of my higher leaves. From what I’ve read it looks like it could be a Phosphorus deficiency. Any ideas? It’s on two out of three plants of the same strain. All same feeding schedule.

I believe I have a phosphorus deficiency from lack of watering/early pH issues. I also have curly/dented leaves that can be seen in the close ups. Does this seem like a phosphorus deficiency or what else may it be?

Brown, curling leaves?
I have no idea what's happening here but the girls are showing some kind of deficiency. Browning, curling leaves. I have two 100w led lights above them and I use an organic dry fertilizer, I recently brewed a compost tea to try to get nutrients to them

Leaf discoloration. 5 weeks old
I transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants? Thank you (nutrition diagram on my first diary)

The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

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 keep turning brown and yellow
It all begann with what I thought was light burn. I then considered it CalMag deficiency. Giving it CalMag did not stop it. My current guess is too low pH due to strip inaccuracies, so I gave it around 8 today instead. What do you recon, why could it keep getting worse?

New grower with questions about burnt tips, browning/scrunching leaves and some pale/yellow spots!
I noticed Quick One had issues with burnt tips and discoloration by the end of week 1 and 2, what could've been the issue? Apple Fritter is looking sick, brown spots, what is that? Easy Bud and Quick on have slight yellow/paled spots on their leaves, only 1-2, is that normal?

Still deficiency? Or wrong diagnosis?
Hi I have a cal mag deficiency it appears? I gave her some calmag yesterday about a half liter (from a gallon/5ml dose) bc she's already wet. How long does it take to correct this? I also have been spraying the leaves. OR did i diagnose wrong?
