Aerogarden and Iranian AutoFlower

First time to give this a try. I've done a few years of soil, figured I would try this. These seedlings are about 5 days old. I'll be putting in an air pump and stone tomorrow. Waiting for my Advanced Nutes to arrive.

Week 2, growing up nicely. Added 1/2 teaspoon each of the 3 part nutes received from Advanced Nutrients.

And an update. I have two air stones, started with the Advanced Nutrients. 1/2 teaspoon of each in a gallon container.

My ph is at 6.4, anyone know what I need to use to lower it?

Starting week 5

As a former Aerogarden user, those roots are going to be much too big for a reservoir that size. Are you planning to transfer them to a larger system?

Im just going to watch and see what happens. Ill post a pic Wednesday, but they have almost doubled in size this week after a water/nute change. At what point will the roots start getting too big?

They are very bushy. I realize I have the rollitup community on edge here, would it make sense to "semi" lst them so the lowers get some light?

I pulled two of the plants and put them in soil to free up some room for the other roots. Plants are doing well, going to put them on 12/12 starting tomorrow.
