did u feed them nutes yet? how close are they to your light(and what kind of light)?

is my first grow please help

i got two flurecents one of 105w and the other of 150 w and the temp is 78 but the other day i was doing someting and the temp went to 90 but i have it on 78 always am giving a normal dose of earth juice grow

how close to the lights are they?

the lights are like five or eigth inches away

but the problem is just in the fan leaves they are turnig yellow little by little and the the brown spots appear

you might be underwatering them because I had the same problem when I was new to coco. I wasn't watering enough.
