Slight burn. You're feeding MORE than the manufacturer recommends and manufacturer recommendations are notoriously over what your plant wants. Dial it back a bit, see where 4mL/L takes you after doing a water only feed or two.

What deficiency is this?
Earlier, I added Epsom salts to fix purple stems, I’m pretty sure I over did it and I think this is a potassium deficiency but I’m not sure. I was being cheap and didn’t change res b4 moving over. Now that they moved tents, seems to be getting worse. How do I fix fast!? Pix in di

Hi guys, my plant is locked, I think it's a nute burn, how can I restart the plant flowering? I also have the Flawless Finish product of Advanced Nutrients, can I use it to flush and restore back the flowering?

Burnt and drying leaves
Any idea what I might have done wrong on the sick mothman maybe nutrient lock or overwatered? It was the only plant without drainage hole and stayed pretty soaked as I was out of town for 3 days. Any advice is appreciated!

Is this light burn?
Is this light burn? If not what is it? It's under a Phillips 13w household led 2700k bulb, it's not the only affected area but it's the most affected and the closest to the bulb. I plan to add more but don't want the issue to accelerate. Thanks in advance!

problems with low leaves
in the lower part of the plant some leaves are yellowing, others are drying out and even detaching. can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering

Necrotic spots
The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

Strange Twisting Leaves
I have a plant that's just over 3 weeks old, and since the first week or so, I noticed it has some leaves that grow with a "kink" or "twist." They all seem to have a small discolored spot on the edge of the leaf that eventually becomes the corner of the kink/twist

Burnt looking seedling
What's going on with my #2 seedling? I thought it could be light burn and raised my light by 4" but the odd coloration on the tips has gotten worse 18hr later. It also doesn't seem to be drinking whats in the coco yet so I'm cautious about feeding.
