Guava Kush. This is my third grow. They germinated fast and I potted them in a soil that I’ve used before specifically for seedlings. Sprouts came up in just a few days and the first week they looked good. But it’s been a struggle with low humidity in the tent. I’ve managed to keep it in the 50s at least. Temp has remained constant between 65 and 70. Now they’re 2.5 weeks old and they don’t look so good. First leaves are darkening, new leaves have yellow tips and overall growth appears sluggish. Is it too soon to add nutrients?

The medium looks wet to me, a bit too wet lol.
Don’t feed them nutrients right now, unless you have them setup for seedlings. I like to use plantstart after day two or so. What did you feed them? If the medium is wet just let it dry out. I’d bin and restart them if they’re two and a half weeks.
I’d say you’ve overwatered them a lot or the medium is too hot for them. Hot as in too much fertiliser. Does your cups have holes in them At the bottom? If not then put plenty in there. If your drain holes aren’t good enough they will just hold onto salts and water. If you do have drain holes, make a light feed with calmag and water, make sure ph is in range and feed until run off. Then check your run off with a PPM/ec meter
Hard to tell the medium and whether it is too dry, or wet? Coco? Soil?
Just a tip, or two. I aim for 80F/60RH for my entire grow(s). You can overcomplicate it if you wish, but shoot for 80/60. Especially in the young/seedling stage.
I have transplanted autos many times with no ill effects. But I reached a point where I figured...why? Planting the seedlings in their final pot just eliminates any unnecessary step and risks. YMMV
