Didn't run into any problems yet. Ran out of soil. I need to put the clones in bigger pots. I will grow all the plants in 3.8L pots until harvest. I don't have enough space and the roots of my last grow didn't fill out the 11L pots so I think it's an overkill to put them in 11L pots.
Hey, I harvested last weekend. That grow was kinda horrible, had molds on the fabric pots (guess I overwatered) and as you already mentioned lots of nute burn. The outcome was around 50 grams(dry) , which is OK in my opinion. Unfortunately I had a lot of unusable popcorn buds. I can't tell anything about the quality since I haven't tried it yet. Guess I'll give it a try this week :) sorry for no updates but I had a stressful time :/
