Hydro 2vast2fast grow

So this is my first hydro grow after my last attempts failed.
Lego
Just planted her in rock wool and some clay pebbles

Yes I know turn lights off before taking photo!

How are you feeding it?

Flora micro, flora gro and flora bloom. Got a schedule off someone else's grow and itll be in the bucket, there's an air pump in there, on, atm. I'll just give it distilled water until I see the roots nearing the nutrience enhanced water. pH is about 6 but it quickly returns to neutral not sure as of why ? Any tips on maintaining 5.6 to 6 pH would be great. Also changing water every 5 to 7 days. Also should I just give it distilled water until it is a bit older ? Or feeding on week 1 is ok?

Its gonna need to be hand fed until it develops root long enough to reach the nute solution in the res. Is there an air stone in the bucket connected to an air pump?

Sure is

I recommend using a drip feed system for your bucket setup since you already have everything but the drip ring stem. It basically automates the setup so all you have to do is keep the res full with ph'd water & the proper nute solution. The waterfall action of the dripping help keeps the res healthy too.

Your going to need to get some ph down to control your waters ph if it is coming out too high or rising on you. Most nutrients have buffers in them that help keep your ph where it should be, but usually aren't effective in low concentrations meant for seedlings etc.
I wouldnt give it anything but water until it has a 2-3 nodes. At this point the plant is concentrating more on roots, and they wont "search" if everything it needs is present. Once it has a few nodes on it, it will require more and thats when you begin giving it nutrients.

I'll do just that, like 3 nodes top it and give nutrition
