No nutrients added, soil contains some compost and humus. Jiffy pot planted directly into larger container one week ago. Plant is about 2.5 weeks old. Watered just before photo was taken.

Discolorations began about 4 days ago, she's growing quite fast, but the discoloration are growing at a proportional rate. Picture attached.

Any help is greatly appreciated! I'm doing only single plant grows, it's save her or I have to start over!

IM not soil but i think you need to add some nutes

Thanks for the quick response! From what I've been reading everywhere most sources state that in a soil grow you shouldn't have a nute deficiency this early on in the grow. The compost and organic matter in the soil is supposed to be enough for the first month or more. Many people don't addnutes till flowering. I may buy some ferts tomorrow.

That all depends on the soil being used, that is not the case all the time. You have to read your plant, if it's looking like it needs fert. then give it to it. I would only give it about 1/4 strangth tho to start and then gradually go up from there.

So you also agree it looks/sounds like a nute deficiency?
