My babies are just starting out and they keep getting a rusty patchy look in spots on the leaf. I've flushed with h2o and sprayed down with h2o and they look better for a day or 2 but then the new leaf comes out with the rusty spots. Could this be too high of humidity? I keep it about 85 degrees in my grow room with a fan circulating air but it is still very warm. At first I thought maybe nute burn and flushed and cut off the rusty looking leaf but my new leaf gets the same spots.

First thing is stop flushing, you need to give more info like medium, what & why you're feeding seedlings, pH, PPM maybe some pictures things like that

Sounds like you are exacerbating a ph imbalance.

85 degrees is too warm

How about that pic?
I'm using peat with rockwool
My hydro mix is 10ml per/gal with 6ml per/gal nitro. I'm using peat mix with rock wool.
My babies are just up from seed about 2 1/2 weeks.
I lowered temp to 75 today.
No pics yet. later on them.
I switched from mh/hps to 2000w LED and I am holding it about 17 in. from the tallest baby. I've been using the same hydro for some time now. I stopped growing for a while and started back up and must have a memory lapse. I can move the LEDS up more but I don't know about these types of light. I'm almost ready to go back to mh/hps-it cost more but I know the grow.

I agree, but I didn't now it would cause those brown spots like that... Could be calcium def possibly, or general under fed maybe... I've read calcium def can happen with LED frequently too, but don't know that personally haven't seen it

Good point... Yeah I'm picturing a certain thing...
I'm using a hydroponic juice called vertigro w/nitro. I may not have gotten all the hydro diluted all the way before mixing for feeding. I don't mind dumping juice and re-doing the mixtures or remixing the juice itself. But I have feminized babies and they are too expensive to throw away. I think I'll flush out the old juice and remix new mixture. The leaf started out turning a dark green in the spots where the rusty spots started. Its only in the center of the leaf and not the edges. But the tip are curling downward and some leaf is twisting. I'll put up pics later tonite or tomorrow. They don't show to good due to the camera I use on my cell phone and I have to goto the top of the hill to get signal to send. Yes, I live so far back in the sticks they have to literally pipe sunshine to us.

does it list what % Calcium and what % Magnesium?
and a really dark green sounds like maybe too much Nitrogen (possibly). maybe too much of that Nitro stuff?
have you used these nutes in the past successfully?
Yes, for 6 years. But stopped for a few years and back again.
The hydro has 3.00% magnesium and has calcium nitrate and has a total of 6.0% and then I am using calcium nitrate 15-0-0. I've used this before and once the babies get about 8" then I use to bump up the hydro mixture. I use to start out at a 6ml hydro and 3ml cal. nitrate and I had no problems. But it seems I remember and also found in some old notes that I needed to start the babies at a reduced mixture of hydro/nitro. It appears I started them at too high a mixture. 10/6 is about what I used bet 2 to fore at 8" which usually took about 3 weeks. And about 2 to 3 weeks later they were going flowering. But, I could be all wrong about this rusty spots and would like all the input I can get.
