Ok... Tell me what ya think!

I flipped these super OG's about 5 weeks ago... They have had yellowing leaves from the start... Nutes are DM gold A and B, Zone... RO water 10ppm.... Water temp 65 I started at 800 ppm, then went to 950 ppm which my Alien OG loved.... I emailed Dutchmaster and was told I should not have to add Calmag.. PH 5.9 ruuning 1500 ppm of Co2 temps 78 - 80, 9k of lights.... I was told to raise the PPMs to the recommended dosage which is 1100... I was then told to try the agressive schedule... so I raised it to 1250 ppms... Nothing seems to work.... Take a look at the pics and tell me what you thing it is..... It is an undercurrent system by the way

I think you have a bad case of KIND BUD, I would consult with a huge bong AS SOON AS POSSIBLE..... DOCTORS ORDERS

dont worry mate, it is nitrogen deficiency, usually happens in flowering, you can give them some veg nutes if your that concerned, but dont worry to much she will be fine. good luck.

Nitrogen deficiency is only usual in flower if you fail to maintain your veg schedule during the stretch. Did you switch to your flowering ferts when you switched to 12/12?

water soluble boric acid 5ml per gal will fix the yellowing.

it is magnesium deficiency dude

Boric acid Dooooode!!! 5ml per gal. you could try epsome salt but boric acid cures all and helps plants way more!!

I don't believe my post was directed toward you,was it?
I simply stated what the problem was....
Something everyone else failed to do...

It is not a mag def dooooode its boron!!!

whatever u say...

It's hard to say if it's or that. I think you been
slightly under feeding all along. I'd run with
1200-1400 ppms then taper it off about 5th
week of flowering~

Its definitely Nitrogen. If your using nutes as directed this is very natural and usually left unaddressed during late flower. Nitrogen will slow flowering a bit and leave a bad taste in buds so in most flower specific nutes its concentration is very low.

Thanks for the responses guys, I will try to fix her up with a littel more nutes and some Mag... I will keep you folks posted.. Donut
