Ive got a feeling this isnt good...

algae maybe? plants are doing well, except one leaf on one plant has spots

how do i get rid of this? if i need to get rid of it at all

try covering the rockwell with clay pellets so the rockwell can't see light I think it should be ok:stoned:

You could also cover the bottom with a paper plate (cut a hole for your plant stem to go through) You don't want to let any light get to the rockwool or your plant roots.

If neither of those fit your fancy you can use spare Panda film (black and white poly) to make little block covers. Only really need to worry about this until you get a canopy going, then the shade from plant(s) will help alot.

thanks guys, i covered it with rocks and may try the paper plate if a problem starts

but all in all my plants are good - the stems are really strong especially :thumbsup:

heres a few more pics of the progress

ps...ive switched to 8 hours off 16 on like smokemypiece said to try, and in like 4 days ive seen a huge difference in growth!

alsoooo a couple leaves are curling and a a couple leaves on the lower part of my tall plant have black spots and are a little yellow and have clearly stopped growing - ph levels have all been maintained

the curling one

Well they picked up quick in 4 days :thumbsup:

Just be sure to pick a lighting schedule u like and stick with it. Dont wanna jump around too much.

I think black spots are either mold or mites. Looks like it might be a little mold. if so, cut the infected areas carefully and get rid of em (Can spread easily thru the air).

Id wait for a nute specialist to chime in tho :thumbsup: Could disinfect the area in the meantime; mites and mold love dirty grow areas [from experience]:hippy:

yup, i think it is mold

its starting to spread a little bit too now the other plant has like 3 spots

how do i cut it? i mean like if its just on the tip of the leaf should i cut the top half off? or if its all over a leaf where should i cut it?

and also how do i control mold? its not to humid in here but again im not trying to control the humidity or temp just yet

in my room it is about 85 on average and i keep a fan constantly blowing

what is humidity and are you in basement, closet, Barn, greenhouse??? 85 kinda on the warm side unless your talking like AZ.

I like Toon's suggestion about the tron not being pre-soaked. i thot i read earlier that you soaked em, but i may be confused. when MJ's young it can be easily influenced by impurities. (thats y i dont use it, but its b/c im too lazy for this step :stoned:)

Id hate for you to cut this early unless its last resort.
