Bubbleponics Seedlings: Coming Along but Need Help!

Hey, getting back to you with the latest developments on my med grow. I have a Bubbleponics system running with a tiny bit less than 1/4 Micro and Grow nutrients added over the course of two hours. The largest front middle plant is Lemon Skunk. Appears to have taken well. The one on the back that is also taking up from was a seedling in a Rockwool cube in my last post, in the back right most cup. Then, next to my ghetto placed (until I can configure it later) vent system pulling air out, and the high powered server fan is blowing a hard stream in that keeps them all moving.

The temp is measured by a digital device to let me know what the temp is at all times. It usually stays in the high 70s to 83F tops. Look at my White Dwarf, the small plant with yellowing pedals. What do I need to do to make sure this one matures with it's sister strains. The three need each other! I water them with a spray bottle several times a day and check on them. Only the Lemon Skunk has more than one white root coming out, the Power Kush will follow. Thanks for reading this and the help.

Specs:
Bubbleponics 6 Gal
600w MH/HPS Lumatek Ballast & Fixture w/ Reflector
Mylar all around
A Bathroom Vent ducted out of the room from the left side of the system, and a power computer server fan is blowing air into the chamber.

Time and nutes suggestion to help the struggling White Dwarf? That is my main concern at this time.

I also just picked up a Accurate Digital PH 2 Meter & Accurate Digital PPM 2.5 TDS Meter from a local hydroponics shop. Apparently they are pretty quality meters, if anyone has any input, please do so. What PPM and Ph would be best for the White Dwarf and other plants to thrive? What PPM is recommended for early vegetative? THANKS! Merry Christmas to ALL!

What nutes are you using?

Right now, I just am using the Nutrient Packs that are pre-measured by Stealth Hydroponics. I know that I should probably get something better, but this is my first time around and I figured from what I have heard, these nutes will be alright.

They include a pack of Micro, that is added to the 6 gallons with either a pack of Grow(greenish-opaque color powder) or Bloom (pinkish poqder). Then, they have provided me with pH Up and pH down, which you add 1 Tsp. to raise or lower a gallon of water by .02.

So far, I have just added the first half of the nutes. I have one plant, the biggest front and center Lemon Skunk, that has more than one strain of roots now going into the water. The Power Kush that is doing well is almost rooting, and the struggling White Dwarf (only one left out of 5 feminized seeds) is hanging on for dear life.

I have the irrigation pump running, and I water them down at least three times a day with just regular, pH friendly filtered water in a spray bottle. I figured that the small yellowing pedal White Dwarf will get better if I pay special attention to watering it. When it was a sprout, it got bent over and the stem was pinched to where it had to be propped. I am thinking that since it is such a versatile plant, it is focusing the development on fixing the stalk right now before it will grow further. What are your thoughts people?

That looks like ph probs to me.

Looks pretty good but seems the rockwool is a little over watered. I would let them dry out a bit and hold off on the nutes for now cause plants can go for weeks with only PH adjusted tap water.

I'm a little worried by you PH up/down and maybe you been given some bad advice. A Tsp of my PH down would do a lot more than lower it by 0.2 and that would be for a 20ltr bucket not per Gal as you've been advised. Normally I mix a drible with about 100ml of water in a jug (giving me PH water of about 1.5) and then use x amount for each bucket that needs to be lowered.

Oh and don't worry about all plants being at different heights, growth etc you can always work around this.

Hope they all make it, looks as though they will.
