Magnesium deficiency You may need to raise the ph up a bit between 6.2-6.5 would be ideal This will allow all of the nutrients to be absorbed better

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!

A deficiency, a toxicity and a toxic-deficiency???
Here's what I make of it (and PLEASE correct me where I am wrong!) : The tips yellowing indicates, a nitrogen burn. The burnt brown tip indicates, nitrogen burned to long 😂 The black spots indicate, a P or K issue (as the leaves are otherwise healthy green in color)

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

Brown and wiltingleaves
Hi, im first time grower of cannabis. Loving the challenge so far, but started encountering some issues with two seedlings and realized im going to need some advice from more experienced growers here. I suspect overwatering or nutriet burn/root rot. Would love for your ideas.

Will they recover?
Do you think these will recover from a plain water with silica,cal mag and microbial flush ? Run off is sitting at 1.8 at this particular point trying to do a flush once everyday to get back to 1.2 ?

Problem with front middle purple punch. Info provided(See description for more); Temp: 71-79.5F, RH: 46.1, DLI: 40-50(decreased today due to tacoing)
This is an organic grow using Coast of Maine Organic plant food, and lobster meal. It appears to me that the plant has deficiencies for all the three major nutrients, or lockout, but today it is also showing what appears to be Calcium or Magnesium. I've been using castings too.

as you can see on some picture some leaves have burnt edges, others are 80% yellow-ish and few have yellow dots. I thought that I gave too much nutrients so I've been giving her only straight water for 8 days and more power light for 4 days. No improvement it's worse now. Please

Blattprobleme bei Pflanze (Wahrscheinlicher Kalziummangel?)
I have 2 plants in the tent and one of the plants is showing quite a few deficiencies. Many leaves are now yellow with brown spots. The other plant doesn't have these deficiencies, both were watered the same, etc. A few days ago, I used dolomite lime and worm castings.

My plant has mass nutrient burn on most of the leaves, I've flushed the roots. Is there anything else that can be done to help recovery or is it to late in flower. Also should I remove all the effected leaves or will they still convert energy for the plant? Thanks

Brown spots and brown tips
Hello. First time grow. I am seeing brown spots and brown tips on leaves. The spots are only on a couple of older leaves. Brown tips on most other leaves. It is a gorilla glue auto in soil. I suspect nutrient problem, but would like other opinions.
