I kinda Chuckled a little at your posts.

Honestly for a 1st time grow you need to get a setup to match your level of exp. One thing you will learn are there are tons of opinions and facts alike.

I personally use full strength ferts as soon as I see rooting. You be beter off in dwc to use half till you can read a plant.
As far as your setup goes the plants are improperly planted- and let me give you some advice. A small plant doesn't need alot of water and it also needs to search water out to grow root. Those little clay balls called hydroton there hold 1/3rd their volume in water. So simple math 3cups of it hold 1 cup of water. Bury those little cubes, plz and quit drowning them.

Now lets take water. PH 6.3. hmm. No good. I think a ph of 5.6-5.8 would be better suited for those plants and dont stand on top of it. Adjusting it for .2 is unneeded.over a period of say an hour get it to the level then check it again in a day or 2. They don't want you correcting it every 5 mins. I also hope that is RO water. If so either use about 1/3rd tap to bring the ppm up to 100 ish. If you tap is horrible use ca/mg to 100ppm or so and then start mixing the fert in. You will also find a chiller works best in that system....

And as far as lighting go crazy just keep it well away from their young eyes.

I think i read you wanted to make a 2 room setup for increased cycle time. I would go with some simple setup for this and pack that room very tight. I use only a few t-5 and t-8

Just keep it safe and simple.

Good luck!

Soil is forgiving for a new guy as yourself. As you learn about the plant and its needs you can then go nuts with faster moving setups.
