1st time aero, real nervous

I'm an old gorilla and new to all of this stuff. I transplanted these little girls 8 days ago. To me they're a whole lot more healthy looking than most anything I've ever planted outside. One shot was taken 3 days before the other and as you can see they're really growing. The one question I have is, those leaves have some curl. Is this normal? DSCN0886.JPGDSCN0884.JPG

How close are your lights, and how are your temps? Curling leaves are possible signs of heat stress.

If your temps and light are in check, you may be running your nutes too hot, causing nitrogen toxicity. In that case, flush your system and use pH balanced water for a day or two, then start the nutes at a much lower strength, and work up from there. Common practice is to start your nutes at half strength of what the manufacturer suggests, especially with hydro, where the nutes are delivered directly to the roots without anything to buffer them.

Thanks JSB99, The light man. said I could run as close as 6 in. but I have kept them around 8 to 10 above tops. I was feeding by schedule and cut back on ppm's when I 1st noticed nute burn. Could I just add PHed water for dilution. Real hard to get my hands on fresh water the last couple of days due to real cold weather down here. Takes me 2 to 3 days to draw 10 or 15 gallons and get it through my reverse osmosis system. I actually thought about just running straight well water. My well checks out at 120 ppm. I do not know what those ppm's are though.

What kind of light are you using?

Fluence spydrx. led. All of this is just an expensive experiment until I find what works. We're in bad shape down here. The legal states are sending all their swag down here. Can't even find brick reefer no more. Got to do something, hadn't had a real couchlock in months.lol Thanks again

Did you soak the hydroton before using it?

What is your pH?

What is your EC or ppm?

How often are you feeding, ex 3 min on 15 min off, 24/7?

Do you have anything you can put on top of the rails to stop light from getting in?

I think I just found the problem. I had gotten out of range on ppm. I just learned lesson 1. Just now drained and added water. Got ph at 6.1 ppm 510 and I run pump 5 and off 3. Thanks for your help dstroy. This is my 1st grow in this type system. I have spare potting holes covered. I soaked hydroton for at least 24 if not more.

Not saying it's too much light, but it's possible. That's a nice LED and 6 in from canopy is probably flower level intensity. You can get similar growth rates in veg with PPFD as low as 450. You can dim the unit to around 50%. If no dimmer, raise the lamp to 16-20 inches. Give them a couple weeks and bring intensity up to 100% at the start of flower. You can even wait until bud set for full intensity.

Yeah, I'd say that was most likely the culprit. That's really intense for plants that small.

Thanks for all the help fellas. I did move those lights up a couple of inches. I will move a little more and monitor.
