First ever grow

Day 22. Both plants are looking good I turned the blue plant so the growth can fill in the rest of the pot. Did some more tucking of the leaves. After messing with plants I can smell It on my hands. Day 24 I've been trying to stay out of the grow tent but when I went in to put my new light up (put it on 50% power) and move my plants over i thought I seen some bugs so I put some diatomaceous earth out to kill anything that may be in the dirt. Also did some lst. Day 26 I'm thinking about doing some defoliation I just dont know with autos. Forgot to take pictures of bz sorry. ( I did selective defoliation to help bud sites with lights) Day 27. Tomorrow is end of week 4 and should be flipping to flower soon. I'm gonna give some nutrients (none with nitrogen. I believe I have a nitrogen toxicity my leavs are really dark and are curling down. I havent waterd for awhile to allow the pot to dry so I know it's not to much water.) I added morebloom which has an NPR of 0-10-10. With some Epsome salt for magnesium. Dont have anything that adds calcium so I did what I could do. I stopped the plant even tho people say not to with autos. I did top to promote growth to the lower parts of the plant.
