What's wrong with my plants? bugs? Nute burn?

So, my plants are about 6 weeks old. Im using an organic nute on it about twice a week when I water. I'm not sure what's going on with my plants and I hope that someone here can help me. I believe the problem is starting as a brown spot and escalating from there. A few of the leaves have holes in them.

its not nute burn 100% sure of that

bugs... maybe... can ya see any? check on the underside of the leaves

otherwise, up the phosphorus a bit, up the micro nutes, and cut back a smidge on nitrogen

hard to tell...keep an eye out for em and as stated above look under the leaves....but that could just be something little with your nutes just use water only for a while and see if your new growth is fine..if its just on old growth and doesnt spread its not bugs..if you start seeing black things or web or if the new growth is getting it as well even though your only using straight water then maybe worry and try to get better pics...

Should I take pictures of the underside? I don't know what would be better pictures.

Those leaves are looking a little wet. Are you foliar feeding them? Even getting them wet and putting them under weak light can cause sun burn in very young plants. I think it could be half the problem. The big concern is why you would be useing nutes on a plants that small. It's just a baby! Your soil looks like prepared soil, and I would be willing it has a fairly high n-p-k before adding nutes. Cutting out the nutes will help. I wouldn't flush something that small and don't let anyone talk you into it, as the shock will probably kill it. Just fresh water for while and see if it pulls through. Meanwhile re- germ, and plant. Usually when they get their feelings hurt this young, they seldom produce what we would like.

Na.. It's probably not bugs. When did you start nutes? This is probably the problem. I've seen this The leaves look like they never formed, and they should have in six weeks. This is from too much n. Your strain can probably tolarate a little more n than some. This is why it's not manifesting itself as a full blown n meltdown. Stunting is typical with plants that recieve slightly more n than what they can utilize. looks like what you have going on here.
