yes get rid of that gnat stuff, if you don't have gnats in your soil then there's nothing to worry about. but if you do have gnats then that probably means you are over watering and if you under water that will kill the gnats in the soil
yes trust me, you only want to water coco lots when the roots have filled out in the pots. When the roots have filled the plant pots you can water a lot of times then :)
nah man don't let it go a week without water. give it 4 days to dry out and then water around the edges of the pot. never water in the middle because that will increase your chance of that main stem rotting
yes you can save it, just let the top soil dry about 1 inch and then water again around the edges. you want to treat coco like soil. watering it too much will drown it and kill it trust me i have about 10 years of experience
you never want to over water coco soil, you want to do the wet dry method just like soil. over watering will cause you a lot of problems. And yes around the edges of the pot. never water in the middle because that will increase the chances of getting rot in your main stem
they are over watered you are loving and caring for them too much. it's totally normal just leave them alone for a while and cut back on your watering when you water them
it looks like you have over watered them a little bit. the bigger one looks better because it's rooted better and probably more established. i would say just try not to over water them. lower your water when you water them. coco likes lower waterings more frequently. Other than that you are...
it looks really beautiful i like how you have braided the main stem, and your artwork in the background is nice too. i would keep vegging them for another month or two if you want to get a massive yield
it's real weed but 80 dollars is really expensive for that little bit he gave you. it's about 50 dollars worth but i guess he's gotta make some money out of it otherwise what's the point of him doing it???
if you want to increase your yield then use more blue spectrum in veg and red in flower. :) higher watts on the bulb and area obviously increase the yield too
