The leaves on the upper plant wake up today with a brownish spot. It’s not light burning for sure (ts 1000 dimmer 70% height 50-60cm). Feeding problems? The first two photos are dark brown, the last one is yellowish.

Based on how dark green and Shiney they are,the leaves. I believe the feed amounts are not appropriate. Vegging npk ratio is 3-1-2. Flowering npk ratio is 1-2-3. If feed amount is not right it can cause ph issues in substrate. Which leads to lock out issues. Good run off is also needed to push old salts from fertilizers out as new is entering. With limited information in question, this is what I can speculate.

hey, It's normal for the thin leaves on top to become a little dry at the edges, but here it looks like the dryness comes from the center. Maybe she had too much fertilizer?

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice 💯🙏🏼

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

I believe I have a phosphorus deficiency from lack of watering/early pH issues. I also have curly/dented leaves that can be seen in the close ups. Does this seem like a phosphorus deficiency or what else may it be?

Please check the last pictures I have posted. This is about a week after transplant, and the plant also has burnt tips. Are the brown spots from something other than transplanting into hot soil? They are in KIS water only soil and I have only been giving well water, ph is 6.8ish

So in the last 3 pics from Day 22...am I seeing a calcium deficiency? She gets tap water, which I was hoping has sufficient calcium. But now I'm thinking I might need some Cal/Mag. Is she hungry for calcium?

Would putting off my first feeding for a day or two do this much damage to the plant? I've given it 2 feedings since then and hoping it's on the right track as the new growth is nice and green.
