Grow_05: Big stress - Big yield

Fungus gnats coming with the soil might take the chance to come out now for breeding. i'm waiting with a 9 mm rifle. in the past i found 6 gnats in 2 of 8 x 50 l biobizz lightmix bags coming out of the soil. i could eliminate every single gnat successfully ;) rotating harvest: the little ones will be harvested completely when ready. at this point only the top branches of the big ones will be cut...and the new (basic-watered) pots of the new grow will move into the tent. 2-3 weeks later the secod half of the big ones will be cut and the second half of the new grow will move in... nutes: biobizz / soil: biobizz lightmix bloom,grow,topmax,activera,algamic + aminopower instead of bio heaven (too expensive) individual feeding schedule/once a week: veg: 200 - 600 ppm bloom: 600 - 900 ppm water: ro-water with: veg: 100-150 ppm calmag bloom: 150 ppm calmag
