HELP! brown spots? 40 days old

[rickbamber]

ffhf soil, AN nute's, cal-mag+., GSC from fast buds, Roleadro 800w COB'S AT 24". I am very much a rookie that is not real sure about these lights. Has anyone used them before?

rickbamber You might want to take some better pictures: I can't really see what you're referring to in those closeups. She looks like she's been growing well so far...

Doesn't look good to me - that's why I don't use hot soil. Toooooo many nutes to me, that's why it's all yellow. My cobs work well at 24 inches - any closer and my plants let me know.

Those aren't yellow leaves, if you closeup the pic; it's part of the pot or something. The leaves look pretty good.

Seems like PH fluctuations just starting to show https://www.growweedeasy.com/ph-fluctuations-cannabis Check your PH runoff for 6.5

I'm not real hip on this camera, those are yellow bug traps on top of the soil. Gotta use the rest of this ff soil. Those brown spots are on the bigger bottom leaves, hopefully it's kinda normal? I will probably be watering on the 28th, i'll check my runoff then. I have a accurate 8 meter, just learning how to use it. I'll go play with it now. Thanks for the info, I've had a few grows, but im very much a rookie.
