Some added RAW potassium. PH at 6.2 to 6.6 but seems to keep doing this still. Its getting really annoying.42 minutes ago

Overcrowded 2x2My 2x2 is getting very crowded and I think I might have overdone it, they’ve been heavily defoliated already and I worry about stressing them out if I do it more. I grew 2 last time and the plants were small. I learned from my mistakes and now the 3 I have planted are huge4 hours ago

Root Booster Terra Aquatica how to use it?my question is how much to water in ml at these stages with root booster, and is it worth alternating this booster with regular watering?
The instructions say to add 2ml per 10 liters of water, or 2 drops per liter of water. and maybe it can be used not twice per grow?Roots. Other

Will my plant die?My baby looks sick :( the stem has completely fallen... I had to add soil around it as well as two tutors to try to get it back on its feet. I brought the plant closer to the lamp and turned on the fan to try to fortify the plant. I hope she won't die…2 days ago
