move the light closer to the plant. the reason the main stem has stretched like that is because it's searching for the light. you need to prop it up with some tooth picks as well
Mexican brick weed is basically made from hemp that's grown out in the wild where lots of males and females grow together. they compress it all together seeds and all. it's probably about 5% THC maximum
yeah that's not safe at all. it could cause a fire and set your house on fire. I would send it back from where you got it from and buy a digital ballast. they are much safer and they don't get hot either
that seedling is under fed. there's absolutely no nutrients in coco soil so what's happening is the lower leaves are dying to keep the top part of the plant fed and alive. it's clear to see!
yeah you wanna flush your plants a few times but you don't have to do it. i just find that it gives you a cleaner smoke. but a lot of people don't agree with me
do you see how all those leaves are yellowing and how the pistols are orange? that means they are done bro. your plants letting you know they are finished. flush them with water for 7 or 8 days and then harvest :)
if you are getting run off when putting 1/4 gallon of water in your pot then it's probably over saturated. from what you have said i just can't understand how your soil can be very dry if you watered them? have you got any pics?
