Any ideas on this?

started grow question 6y ago
I'm guessing this is some sort of deficiency. Some of the spots are rust like and occur and young and old leaves. Any opinions? Advanced Nutrients 3 part. No supplements.

Looks like Calcium deficiency to me mate I'd foliar feed the leaves with some calmag and some chelated iron couldnt hurt either

I agree calcium deficiency is most likely the problem. Calmag will solve the problem.

Brown Spots on Leaves
I’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

On lower leafs some brown patches started to appear and leafs are turning to a yellow color. Think is either Cal def by how it looks like or it is because of PH fluctuations as last week we changed our PH to 6.2 for 4-5 days and now it is back to 5.9 and under 24h spots appeared?

Leaves dying
I removed these dying leaves, they were burned, with signs of necrosis and curling down. Now the plant siting next to the "sick" one started to show some early signs, similar to what her sister showed weeks ago 😪 Does anybody know what is going on?

Cause for mottling leaves?
I think this mottled leaf coloration may be due to slightly high pH or just stress from the repotting over the last couple of weeks.. Most leaves are fine but a few look like this. Any thoughts?

Noticed small brown spots kind of center of leaves, noticing some kind of chewed up deformed leaves now. From what I've read it sounds like leaf hoppers? Has anyone else had a similar experience?

I'll just leave this here.
Only a few leaves, but should I be worried? Last few waters have only had calmag to see if that helps.

Hi growdiaries, Got a couple of issues on my plants here. The last 4 pictures show the problems, firstly there are holes appearing in the leaves and it looks like something is eating them. Haven't seen anything alive. Also a few spots appearing. Mould? Had bad air for a bit.

Leaf changed color and spotting, help!
Any idea what I need to do to fix this? I think I over fed and then I recently did and RO flush. Then I fed it calcium herkley and harvest recharge in a little general organics bloom.
