Sorry for all the messed up posts. Im still new at all this fourm stuff. 1st grow

Need help with first grow. Lowdown- stealth hydro system 8 gallon resivour. 3 plants on a 400 watt Mh light with 21/7 light cycle. Water pump is running 24/7 more then a drip. I was told to leave on for 1 month all the time. I think its starting to mold. Please help.

whats getting moldy?

Trunk were the water drips from. I know im watering to much but how much is enough?

3 plants are going to crowd that bucket quick when you switch to bloom. im doing 2 right now in a 12 gallon and running out of space for roots at 35 days flower. just a heads up. and if your talking about your tubes getting mold/algea on them, ive had that issue too. make sure no light is getting to your water. it will also give root rot with this. i just make sure to clean my res and tubes weekly. and when they are young where the foiliage will not block light cut some cardboard circles to cover the holes. GL on your grow
