I'd add some cal mag to the mix. As it looks like magnesium to me but I definitely could be wrong. Check out the link below to help trouble shoot https://www.ilovegrowingmarijuana.com/nutrient-deficiencies-in-marijuana-plants/

Hi! I have spots forming between the leaf veins. Most are a red/rusty color and necrotic but a few are purplish red and still flexible like the healthy part of the leaf. The only affected leaves are near the top of the plant but not the very top either. Do anybody have an idea?

I am noticing a weird discoloration on one of the plants. It's starting from the edges of the leaves and growing towards the middle. You can see it in the last photo. I have looked on a few guides, but I haven't been able to find this issue. Can you see what's wrong?

Q1) My Dinamed #2 is looking a little concerning. Been spraying with freshly made neem water. You think its leaf miners or could it be a mag def.? Q2) I'm seeing yellowing tips on some plants (old full-leaf yellowing from pre-transplant). What could it be? Organic nute burn?

Hi Growing-Community! Today I detected small brown, rusty spots at the top on new leafes (see pictures at week 4). Anybody any idea what could be missing my Nothern Light-Girl? I transplanted her to 11l-pots with BioBizz-Allmix last week and gave her just water (PH 6.5)?

The middle plant is somehow very bad off, while my other 2 plants seem fine, making me think its not humidity/nutrient related, but i really cant imagine what it would be, has anyone experienced this before? it went from perfectly fine to this in just 4 days.

The young seedling leaves seem to have some sort of bruising. The young fan leaves are fine though, is this something to be concerned about or is it quite normal?

There is some damage on the first set of leaves, I was thinking it's either due to fungus gnats which I am in the process of eliminating, or an early cal-mag issue from before I increased my nutes. Any thoughts?

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?

Plant #3 (pic above) started as a sprout with discoloration. Now on its 4th node, the plant is still affected. Some other plants seem to have it to a lesser degree. I learned it may be TMV, but they are healthy and growing well other than this slight discoloration. Any thoughts?

Need advice as soon as possible. Please see last few pictures of DoSiDos week 3. Am I looking at mottling here? Soil ph maladjusted? Please help if you've seen this before, and what steps do it take moving forward (or am I paranoid, IDK). Thank you!
