Too much light?

[ClaytonNewbilFontaine]

Thanks man, she's definitely got a couple issues but I think she'll pull through.

I got a decent bit of yellowing and the dying leaves this time around. It would be 3-4 leaves at a time but it happened consistently through flower. I never did figure out what I was doing wrong. It was thinning it out for me so I didn't stress too much and it was never more than a few at a time. But I did want to try to figure it out. I kept going to something with the roots or the soil. Maybe salt build-up. I couldn't ever get any good pics of it bc I left the canopy to thick and they were all at the bottom. I'll stop back in later.

Most likely Nitrogen shortage.

Yeah I'm thinking she's burning lots of energy with flowering. She's loosing lower leaves and the ones she loosing look smaller. What are you feeding her with?

I wouldn't worry about the leave edges too much if your parameters are okay. I'm at 78f today at canopy and the humidity was 60%. The plant is 24" from a 240w long board dimmed to 175w in a 2x4 for 600umol/s so there's no heat or light stress and leaf temps should be fine, but they show the same heat stress issues.

I noticed it happen a lot during pre to early flower as well so I just roll with it.

Ff trio plus ff flowering nutrients. The leaves she is losing are smaller ones.

Are you following their recommendations?

Top dressed 4tbsp Dr. Earth 4-6-3 & three handfuls of new Ocean Forest soil about 16 days ago. So that should be available right about now. Then once a week I gave 1tbsp of liquid Fish & Kelp fertilizer.

No flower girl in the top dressing? I've used the Dr. Earth veggie (green bag) along with the flower girl and had pretty good results.

I talked to @Lenin1917 & he said he got better results just running the 4-6-3 all the way through. Along with Fish & Kelp + Molasses. I can get Flower Girl if I need to.

Indoor light vs the sun is like bullying vs the Military or Sports team. Plants in the sun will almost always be fine because it's diffuse. Indoor light is like 4 guys beating up a little guy in the bathroom and it can be brutal because it's so focused.

Ok so aside from light/heat issues up top, the yellowing is spreading to almost every leaf directly in the "center mass" of the plant, from the bottom up.

Is this too much nutes or is it starving?

I had that problem a lot and I think mine was nute related but I'm not 100% sure. That's the bitch of the bunch. It can be like 5 or 6 different things.

I'd be more worried if it were happening higher up, but I would still try to pin point the issue for your own sake

Yes, mostly. I started off at 1/2 strength. And added Mr fulvic and PowerSi throughout the grow. There's 2 different ff feeding charts, both look like their from ff,I think ones older. They're slightly different. I would use the one that made more sense judging from what the plant was telling me. From the very few words of hers I've learned.
