First Grow with some problems: Pineapple Express

This week I was on a small work trip but the plant did very well. I can safely say it recovered from the errors in the beginning although they surely set back the growth. I am going to send it to flower next week even though it could still grow a lot to fill out the grow tent better. But since it's legal in Germany I am already planning my next grow with three plants which will use the light and time better than just this one plant. I also watered with nematodes so the fly larvae hopefully get killed. I tried to leave the soil as dry as possible which usually helps with the flies, but my watering is still frequent enough for the flies to survive it seems... Next time I will do some preventative neem oil watering in the beginning of the grow. I had some positive results for other plants with it in the past.
