It's my first grow. 6 weeks from seed, still in veg. Fox Farm HF soil in 1 g plastic pots. Watering every other day. Started feeding 2 weeks ago with Mega Crop, every watering at 2 gram/gallon. They are often drooping, seems to be random. Humidity has been 15-30%, temp 66-75F (19-24C) Saw first signs of yellowing a few days ago, much worse today. Can't get pics until tomorrow. Opinions? I posted in the newbie section and are people asking about humidity and telling me to re-pot etc. etc. but no explanations.
