I read the guide and I'm still unsure what's going on here. Any help would be greatly appreciated.

So I'm trying out dr earth and coco loco. I mixed it in the soil at the beginning and at the 30 day mark 4 days ago i topped dressed. I've been adding microbes and mycorrhizae sporadically.

They all seem fine except this guy. - there is the difference between the leaves

dr. earth needs time in soil before planting to break down. yellowing of the very top usually means low sulphur so a small dose might be a good idea. usually it's mixed in with other ferts though. not entirely sure that's the issue. hard to say right now. need more details and few more pics.

So I grew indoor all winter and I'm taking advantage of the summer sun here in Colorado so I've been growing these in a greenhouse with led and natural sunlight. Honestly it seems like this just happened since i top dressed. I gave it microbes, bud candy, and this stuff that's black powder. Regen or something - also microbe shit so i was thinking it was a excess rather than a deficiency. But I've been strictly at 6.0-6.2 ph. I don't get it

Could be early stages of lockout Nitrogen would be guess, but only a guess nmi!

Shit I am almost thinking sulfur as well. It's odd for such a young plant.

I figured it out man. It was overwatering. This is my first time with coco and I've been reading that you can't let it get dry. But i was keeping it far too wet. I just stopped watering for 4 days abd the color is coming back.
