thanks. good info. applying this regimen once a week?
i had mites in previous grows, and they are always pretty noticeable. and the damage shows like a lot of small yellow/white dots. and i have looked the plants, and haven't found any bug.


the photos from three posts ago, are from the same day (yesterday). i'm re posting them below. the only change is that they grew a little more.

They look like they do have an odd variegation. That is a mutation, that's not going to go away..

Kinda reminds me of the "crinkle leaf" pheno of Clockwork Orange......Auto's though..eh? I'm thinking genetic variegation??

Feed them right and run them out. Not sure your going to get rid of that...

Hi, it has pass around a month since they sprouted. The "variegation" hasn't disappeared, but it's barry noticeable, a couple of leaves here and there.

But about 4/5 days ago one of the northern started to lose color. The newest leaves became a lime green, and a few of the oldest one start to yellowing from the tip, and a couple of brown spots appeared.
The overall look is not that bad, but i don't want to let it keep spreading.

I have feed only 2 times, the 8/25 i used 9-4-8 veg and a root stimulant, both with micro nut, both at 2ml per gallon ph 5,5-6,0, and the 9/2 i used again both at 4ml and 1/4 tbs epson salt ph 6,4-6,6. like i was recommended. The jack and the other northern responded very nicely, with a much deeper green. but i don't know what happend with this one.

The fact that it started after the feeding suggest excess, but it was pretty mild, and the others are fine.

Any suggestion?

Thanks!
