Sure thing. Thanks for the tip. I've been giving them plain (rain) water for about 2 weeks that is within the desired ph range. My problem is, I'm getting anxious. This is my first grow ever. I'm trying to learn how to determine when to harvest by the trichomes. I only have two plants. Northern Lights (autos) planted in coco, perlite and vermiculite. I use GH for nutes. I think one mistake I made was starting them in a 5 gal pot. I've been monitoring the trichomes and, I'm seeing the amber slowly creeping in. I should harvest before the trichomes are predominantly amber? I should want to cut them when the trichomes have changed from clear to white. It's kind of hard for me to determine. I don't want to mess this up. By them being autos, should I treat them any different (trichomes) when it's time to harvest?
