Burned top leaves with cfl bulb

Looks like nitrogen deficiency, try more vegetation nutrients.

Should I give 1/4 dosage or 1/8 dosage?

Bump it up!

Updates on my girls. I went to water today and I noticed little black bugs in the run-off dish. They were only in the soil and not on the leaves. Some of them did/didn't have wings. I went to greencoast and they suggested it was root aphids and recommended Green Light systemic insect killer. I applied the pesticide and then I flushed them 5 hours later. I hope I get rid of these bugs. = /

I checked the soil today and no signs of bugs anymore. I switched to RO water. Ppm is 4 compared to 100 with the other water I was using. The employee at greencoast told me to pick up some cal/mag to bump up the ppm to 150 and then raise it to 850-900 with grow big. Is this correct for first time feeding and 3 weeks into vegging today? Any advice will help. Please and thank u.

No one has any advice?
