Why are leaf tips curling down?The leaves on one of my plants (Astrid) are curling down and under. Her leaves are also smaller. The other plants are fine. They're all White Widow and they've all grown under the same conditions. What's wrong with Astrid? What does she want?

When do you switch from veg to bloom?How do you know when it's time to switch from veg to bloom? Mine germinated 8 weeks ago, but they had a bit of a rough start in life, so I don't mind giving them more time in veg. But is there some way of knowing when it's time? And is it possible to wait too long?Week 7

pH is high - how to bring it down?My pH is high (over 7) in both my soil and water. Should I adjust the water/nutrients to the target level for the plant (6.5) or should I adjust it lower to bring it down faster? (BTW thanks to everyone who has answered my questions so far. It really helps.

How do I lower pH using pH Down?My soil pH levels are high - just over 7. My tap water is also high - over 7. I have a bottle of pH Down but I've never used it. Do I just add a bit to the tap water and water them? Or should I wait till the next time I'm adding nutrients? How much should I add? Thanks!

How much water do they need now?How much water should they be drinking now? Does 2 cups every other day sound right? They're in fabric bags and the soil is a combination of CannaTerra and Promix HP. I've been paranoid about overwatering, but now I worry I'm underwatering.Plant. Other

Why is week-old seedling starting to fall over?Why is the seedling in the foreground falling over? Is it from stretching? I planted it on January 28, and moved it to the tent a couple of days ago. It was doing fine until yesterday. (I've removed it from the tent and put it back under the CF bulbs in the bathroom.)

Why did my seedlings all die?My seedlings all died. This is the second time. What am I doing wrong? They germinate, I plant them in Promix HP soil, they pop up in a few days. I move them to the tent. Most of them never even lose their seed caps before they die, but a couple get real leaves first.
