That to me is your plant isn't getting enough phosphorus. Bump bloom nutes up just slightly. But if it was me I would flush with plain pH water before raising. That way you can eliminate any salt build up and old nutrients and replace with fresh

Get an EC/PPM meter. Hard to say with no feeding strength data. Yellow leaves (chlorosis) with rust spots in the bottom leaves is potassium deficiency, which is normal in flower stage. You might be getting burnt tips because the soil might be too prefertilized with nitrogen. I would stop the veg nute and focus on the bloom for now.

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?

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?

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

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?

I just found a spot that is making me think bud rot. I so hope it's not true. Slight discoloration of pistols and leaves in a bud node. I added a picture in this weeks section. Please tell me it isnt bud rot.

Why did my pistols turn red so quickly? I did add some neem oil and recently began running CalMag but immediately stopped... Finally got ph tester and realized I’m running way to high. Got up/down coming. Any ideas??? Should I worry or do anything? Also, no males in there

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.
