Nute Def?

Got a plant that looks like something is definately hurting it in some form or another. Thought I'd let you guys take a look and give me an answer to my problems. I don't even know how to explain it. Can't be a nute burn, I've only given it a small portion of a 10-10-10 twice, and I mean very small. Although, I added some slow release pellets that were high in N a few weeks back. Maybe the pellets are kicking in and hurting it? Also, I had a few wasps chilling in there for about a week or so, they ended up leaving these little white things, perhaps eggs. Before they arrived, as I can remember, I didn't see any damage to the leaves so you never know, it could have been them somehow? Or just nute prob? Temps vary from 21 C - 29 C daily, can't be a stress problem could it because of the temps?

Thanks for any answers to my problems! You guys are the best.

Would it help any if I sprayed a light mist of water on the leaves with the lights pulled farther away for an hour or so?

Edit: I tend to spray some water on the bottom leaves while I'm watering, maybe this could be the prob?

I can tell you for sure that they are hungry. But the 10-10-10 is not great. Find something with midronutrients in it and a ratio with the first number higher than the other 2, and not TOO concentrated, and give it as a foliar spray a couple times too, plus a regular feeding.
I'm concerned about the soil- it looks bark-y. What is it? What's the pH? I think you are starting to see symptoms of calcium def or lock out.

your PH is out , causing lockout

complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...test the PH of this water....

If the PH reading is out of optimum range 6.5-6.8 PH, you need to flush your plant.
Flush with PH corrected water, till in optimum PH range, 3 times the volume of the pots rule of thumb but may require more
EG: 1 gal pot = 3 gal. flush

add 1/2 strength nutes to the last gallon of the flush.

Thanks a ton for the info guys. ONLY problem is, the pot doesn't have drainage holes! After potting the plant, I read on the soil package that I need to put pebbles in the bottom, which I didn't do. So what can I still do without drainage holes? I could always cut a few myself. I'm going to go out and get myself a PH test kit. Glad you guys replied.

cut the holes......
