First Time growing 8 GSC in Superponic system.

imho...get more lights. It at least throw a mh bulb in your hood allong with your t5's. It's good to be cautious, and get feedback so with the distance of your lights at least if your t5s are 2 feet away you are depriving them .in your pics the have major bad stretching your hps/mh yes should be anywhere from 10-18 inches away for perfect lighting...maybe more on the 15-24 inches since they are still considered seedlings and barely show a full mature set of true leafs. Your t5 if your using the t5 allong w mh or hps or as a stand alone veg light you can set them right ontop of your girls max four in away. With them that young I'd start w 1/4 strength nutes for the first two weeks then half strength after,...too much nutes and not enough strength from lack of lighting small dangly little fluffy popcorn bud plant...looks like dwc so you at least have that advantage, I as well as many other will suggest to keep your water temp under 70° at all times. Or pythium ( root rot )will set in.....with 8 gsc in a 2x2 tent, I hope you plan on keeping them maybe 1 foot tall . because for max growth quality and potential you will need a tent at least 6ft long 4 ft wide and 6-12 feet tall..your girls are feeding off all that you give them. So I personally would drop your t5to about 4 in.from plants.since they are still so young if you veg with 150w mh bulb keep that 2ft or so awayaway....you said on week four...did you started counting the day it (popped) out if dirt correct?..you may be continually shocking it too by the transplant and boost of nutes. Get that light on them and nurture your baby's they will pick upgrowth spurts it will seem like nothing for a week or 3 and BOOM then slow again. Dunno I'm babbling and in a rush here at home. But all in all if ph is right and you go back to 1/4 strength and drop your t5 closer wait a couple weeks and you will see a big change...and I can't stress how bad root rot is even when you think everything is perfect it will fuck you and have you on your knees crying. I have soil and 12 site rdwc...hope you get some more answers soon . but they look fine just drop those lights closer

 

heres mine, and my babies are 4 weeks old I have autos in too and they are flowering so my 600w light is maybe a foot away from the highest bud, my babies are getting plenty of energy w it being 600w. Once those autos are done and out I will throw 2 1000 w mh/hps and finish veg then flower and I will keep 1000w only 18-24 in away...so as you see your t5 too far away your 150 watt will be fine for veg but with 8 girls you need at least 1000w to bud and get a descent quality and yeild.and space!

 

Welcome!!!! Im new to grasscity but i have some experience in dwc, rdwc, and airo. Id like to share my experience. Take things slow and never change multiple things at one time. It makes it hard to identify root causes of issues. Every grow room can been looked at in 2 parts. A ryzo sphere, and atmosphere. You need suitable water and oxygen supply to the root zone(ryzo sphere) to sustain healthy steril roots. The temp. Of the water resivour is important to fighting bacteria and maintaing higher levels if disolved oxygen in the water. 58°f to 68°f is the temp range you want to be in. The amount of disolved oxygen that the water can support begins to drop off above 68°f. It becomes unsustainable to support life above 73°.(common temp for non chilled rez) above 73° also marks the peak temp to support bacterial life.(the enemy). Your plant may not respond well to a temp at the 58°f to 64°f, can be stressful depending on strain and room enviormental factors. Adjust your temps 1 degree at a time, 1 a day. Always use RO water. Always. Supliment with cal mag(botanicar cal mag plus 2ml/gal),check ppm or ec, then add base nutes.
I like to start my clones in a rdwc veg system, chilled with about 500ppm, room temp 75° to 80° with humidity 50% to 75%.
Flip your water every seven days if your rez is not chilled. You can run as long as two weeks with a chiller and steril aditives.
PHing your water depends on nutes and water source.
I need more info to relate to your set up.
About any problems you may have, when in doubt, flush it out. Drain all water and replace and add nutes to 50%.
I like synthetic nutes, cyco, current culture, dutch master, advanced nutrients....i like em all for different reasons.
Dont use nutrients that are derived from urea, these are not usable for the plant with out bacteria consuming it (the enemy). It will cause rez problems.
Ill end here. Let me know if you would like me to continue. Hope some of this help as well. Post some pics of these ladies up to dat as well!

this diagram is for hps lights. With 150 hps you can get desently close especially if you have an fan sucking heat out. With your girls still young and fragile I wouldn't go any lower than 15 in as they grow keep lifting the light a few in. Here and there but they will also start getting hardier so they can take a little more intensity so maybe week 7 you can cut back on how many inches your lifting the light as they grow

 

so as you see when they get strong and start to bud you can get as close as 4 inches!!!! Imagine the calyx and trichome production with your lumens pumping thru close like that!... Well we all know to get our research and ask questions next trial and error to success ....

 

How do your roots look? How far into the rez are they? If you started these on 1-11 then you are on the start of week 3 today Feb 1. Not a big fan of TechnaFlora's RFS. Just way to much mixing needed for a new grower which I assume you are. K.I.S.S. when you are just starting out.


Due to your very limited lighting switch to a 20/4 or a 24/0 light schedule. You are never going to grow 8 GSC's in a 24x24 area. Any company who would sell a product like this with 8 pots in that small a rez assumes you are growing peppers and NOT cannabis. Weed out your 5 weakest plants and focus on the 3 strongest. Even that is going to be hard in that area with all in a common rez. Frankly 2 GSC done right would be very very tight in that area. Granted you have some control over plant size with photoperiod plants with veg time length. But first and foremost we have to get your plants on track and thriving. Are these fem seeds or do we need to take into account sexing still?


Also let's get that ph down to 5.8.

 

I just realized this was a SuperCloset box. Sadly you could have built a larger cabinet with the same or better gear for about half the cost.


If your girls don't even have roots into the rez yet at their age we really have your work cut out for you. Just for reference I have a Bomb Seeds Cherry Bomb in a 3.5 gallon Bubble Bucket. Simple General Hydro Grow, Micro and Cal/Mag. She is at day 14 and her roots are 18 inches long in the rez.


We have to figure out the cause for the stunting and correct the problem. Get as much light on them as you can. As long as you are dealing with feminized seeds cull the 8 down to the best 3. Get that scrog netting out of the way(I can't believe they really send a net with 8 inch openings it's almost an insult) Drain the rez and replace the solution using just GROW. Set your ppm to 125 because we just don't know where they are at this point. We gotta' get them growing and into the water.

 

......and what did they tell you?
