Yellowing/Browning leaves on seedlings--Bluecheese\A-Train--

Like the title says. All of there feedings have been ph'd reverse osmosis h20 except for a splash of 1/10 strength technaflora veg formula, witch was only done once. Soil is SunShine pro mix. All 4 are 2 weeks old from germination. +rep for any good advice

Bump....... Anyone?

...how often do you water them? They look overwatered to me.

I water when they feel lite... Maybe once every 4-5 days. They were transplanted and flushed a few hours before I snaped the pics, so there drenched..... Im starting to think it's a deficiency because sunshine mix is a soiless mix... But another part of me is saying its nute burn from that splash of ferts I gave em.

Do seedlings need nutrients???

yes that looks like nute burn. u should do a little flush. seedlings do not need any nutes other than the ones in the soil for the first 3-4 weeks

the soil will be able to support the seedlings for a month dont nute yet your gonna fry your seedlings xD

a splash of 1/10th nutes wont cause shit like that. i'm not sure whats in your soil mix but you have a deficiency. find out what's in your soil, if it's not much start feeding it at 1/4 and work up 1/4 each feeding after. feed every other watering like normal and make sure your nutes have the micronutrients(ca/mg) your plant needs.

What kind of Cfl are you using? How warm is it?

Good advice +rep... The soil ingredients are Canadian spagnum peat moss, perlite, dolomite lime, gypsum, and wetting agent. It's a soilless mix so there is no N-P-K

I got 8 23w cfl's in that 20"x20"x20" cab. 6 are 6500k, and 2 2700k. There running 24/7 and temps stay around 77-80.

I don't know whats wrong with em. I'm fealin like they need nutes, but I dont want to burn em.....

Here's a few girls I got flowering right now. Around 3 weeks in..

Looks to me like they need too start getting about 1/4 strength nutes, since your soiless mix has nothing in it the seedlings are looking for some nutrients........thats why if you look at them, the bottom leaves are turning yellow and the tops are still green, if it was nute burn all the leaves would show yellowing. Thats my take on it...Good Luck!

+REP....This is the conclusion I have come to as well. But just to be safe i am only gonna feed 1 of each strain. So ill have backups incase I fry em. I'll get to the bottom of this one way or another. Thanks to all who commented...
