After transplanting the plants to their 3 gal pots last week I topped them early this week. I actually topped one plant, and FIM'd the second one. Both plants slowed their growth as predicted for a few days afterwards, but they are both now growing quickly. I'm using cut up coat hangers to do some basic LST and it seems to be working.
This week I watered on Monday, Wednesday, and Friday. The first two waterings I didn't get any runoff, so on Friday I watered them much more thoroughly. I adjusted my larger fan to now run all day instead of just during the day in order to further dry out the bottom of the pots, as they were still wet the day after. I'm using PH test strips to test the water and the runoff, and both seem to be around 6. I'll be upping the dose of nutrients slowly over the next few weeks to 1ml/l each, for now they are at half strength.
Next week I'll be installing the screen and perhaps another top closer to the weekend if the plants are ready.
