All you need to start is earthworm castings, molasses and mycorrhizae. Molasses you can get from any grocery store. They sell horticulture grade molasses, I have some but that is because it was gifted, but I used to use normal unsulfured molasses. Sulfur is a benefit though, it is not common to get a Sulfur deficiency, but i have experienced it in the past, with 2 strains in particular.

You can get worm castings from any good nursery, molasses you can get at the grocery store or hydro store, I know the Hi-Brix by Earth Juice is thinner and easier to pour, it is also a very reasonable 18 bucks for 1 gallon. But if you get the grocery store stuff just pop a pre measured amount into the microwave and heat it for a few seconds to soften it up. I like to use a ceramic espresso shot glass for that. Mycorrhizae you can get from a variety of hydroponic outlets and from high end nurserys. You can find it in a liquid or powdered form, but powder goes a lot further. The best part about teas is that you only need a little bit, the idea is that it breeds and multiplies in the bucket so you can make a product that is only good for 50 servings, and make 150 servings out of it.

Optional and recommended additives:
Sea Kelp extract (powdered is preferred for this application)
Guano; bat or seabird; I prefer Jamaican Bat Guano for it's high PK ratio
Fish Emulsion
Nematodes, they defend your plant from fungus gnats and root aphids!
Any product for plants that says "microbe," "bacteria," "fungi," and of course, trichoderma.

Hell yeah dude I am stoked for you! Make sure you read up real good on using this in DWC/recirculating/undercurrent systems to avoid any complications down the line. Did I ever link you that Heisenberg Tea thread?

Smell and film are the two biggest problems. Look out for a film forming on your water surface, look out for root slime, and be extra sensitive to foul odor. The slightest foul odor can spell big trouble in the future, but if you get a faint waft of it, change reservoir immediately, if you catch it early enough, nothing will happen. Keep air circulation and water circulation to a max, anywhere the water isn't churning means that the water is going stagnant, and that needs to be avoided. Anytime crud appears, investigate it to see if it's food forming or a problem. There are a few issues that were addressed in that thread actually. Keep reading through the thread, even the stupid questions.

I use Heisenberg's tea and I don't see anyone talking me out of using it anytime soon. It's magic. Tired H202 once and the slime loved it. Won't do that again.

Alright looking good! Those are some happy roots right there. That little bag seed you put off to the side really took of to be the star of the show, didn't it? That thing is a monster, has some fatty kush leaves on it.

But yeah, the roots don't mind the brown dots at all, and they will all rinse off for the most part when you give them their first fresh water flush. I was so jealous of all the threads I am in now because everyone had beautiful seedlings but me, so I went ahead and germinated 12 of my finer seeds for a whole new generation of seedlings!! With all these fresh mom's, I've almost locked myself into selling clones for the next few months so I don't go way over my limit. But I plan on cloning and testing them all!

Those are some really really happy young vegging plants though, you are doing a great job. Blowing most 1st timers out of the water and you haven't even hit flower yet. It is waaaayyyyy to early to say this, especially with all the new challenges brought on by your first flowers, but I think you might have a knack for this whole "Growing Ganja" thing.

I think you mean 1600w, not Kw

Good luck!

Looks good, man! Will you flower in the same setup or going to move them around?

Clone for sex under CFL, just pop them in a cube with rooting gel under 12/12 and they should show signs of sex as they root under 12/12 within 2 weeks, make sure you properly label both the mother/father and the corresponding clone. Once you find out, throw the clones away, clone only your female plants, label them, and then throw out your males.

But believe me, when you see bananas, you know they are bananas.

Your plants look good and healthy, one is a little droopy, and the rest seem to be over transpiring. What is your RH and your PPM? But it is good that your PPM and pH are rock solid, they should be with that much water in the system.

look it up on your tube on how to properly clone but you use a good branch that is well developed. RH is around where it should be, 50-60% is best for veg, but 48% should be fine. The PPM's could be higher, bump them up by 100ppm and see how your plants respond. I could explain cloning, but a video makes it a lot easier.

Light control the area the best you can, it doesn't have to be perfect, but make sure it is at least dark. Outside plants get moon light, so as long as a light leak doesn't illuminate the plants you should be fine.
