With fertilizer... for example I use the full line up of emerald harvest 3 part system. Also I 100% always PH my water. Because only at a certain PH your plant will take up the maximum amount of nutrients you feed them.
I would check that’s what it looks like. That shit is next to impossible to keep it under control I’ve had bad experiences. With wpm!!!! Shits a nightmare.
Happy frog soil, or fox farms..... also superstore or places like that sell very good soils you just have to pick a choose and read the bag before you buy it. I always go with natural soils ...... never MG... not for this type of growing. Feed your plants yourself and never use time release...
When you look at the tricoms... I always try and get as close to 50/50 amber and cloudy. As possible. Also I do believe in flushing for atleast 1 week. But I try for 2.
I also was ver impressed with the Finnished product. That emerald harvest is great stuff. Works very well and super easy to use. first pic is about 3 weeks from Finnishing and second pic is and 4 or more weeks.
