Brown dots on leaves
Dylon
started grow question 4y ago
Getting some brown spots on leaves, thought maybe it was septoria so have been treating with neem oil. It’s still slightly spreading though, not on all leaves. Also a couple brownish/bronze patches. Any idea on what it could be?

This is a calcium deficiency - has nothing to do with insects... add some calmag and you should be good to go.. Good luck!

Yellow bottom leaves/brown spots on bottom leaves
Hi guys, So 4 or 5 bottom leaves of my 7thWeek autoflower looked like this and I ripped them off. Is that ok or did I harm her? Anyway, is that a Calcium def? Should I give her some CalMag? Could it be something else? Besides this, the general condition of the plant is good. Tx!

Fan leaf finger progression
I read somewhere that a healthy plant should increase fingers with each set of leaves. Wendy had two 3 fingered leaves, one of which wasn’t clearly defined. The next set of leaves look to have one with 4 fingers and one with 3. Should I be worried? Does she look healthy?

These spots have appeared for a few days now, both at the bottom and the top. The last runoff was: EC: 1.00 pH: 6.3 (EC in: 1.10; pH in: 5.6). I suspect a deficiency of P and K, but I'm a beginner and I'm not sure. I use coco and perlite with Terra aquatica tripart + calmag. 🙏

Spot on leaf and white tips
Should I be worried about this spot? It is just one leaf, appeared today, and i've noticed some tips got white/yellow. The latter appeared before any feeding was done. I've only watered with tap water and Power Roots. Nothing else was added until today. Plant looks great otherwis
