pineapple express getting worse!

Hey everyone, got a pineapple expres that has been yellowing for about a week and now is looking really bad, getting worried about my first girl!
Went into soil mar 18, bout 5 weeks old(supposed to take 65-75d). She is under a pro grow 260 led and a couple of cfl. In 12.5 l airpots, soil is a mix of sea soil essentials(www.seasoil.com), worm castings (www.nuturingnature.CA) and perilite. Watering is done only when soil is quite dry. Using advanced nutrients mostly organic. Got iguana juice bloom, sensi Cal bloom, organic b, sensi zym, tarantula, piranha, voodoo juice and nirvana.(I know might have gone overkill on purchases
Haven't gave her nirvana yet, all others started at 1/4 dose, been bumped up to 1/2 last week hoping to fix the yellowing. From all I read seems like n Def but more iguana hasn't helped and were well into flowering. All in all seems healthy but worried that yellowing has spread and might lose a lot of leaves before she is all done! Anybody got ideas??

Oh ya, started watering with ro, quickly realized should just use tap, ph is 6.7, using a pump to airate water, one thing that I'm not sure about is ph of runoff. When I first got ph meter runoff was 5, tried flushing soil, only bumped up few points, runoff is still low, but I have read that that is not an accurate way to measure soil ph. All ingredients should have a neutral ph so I don't get that

Hi there looking at your plant i would say you have overferted badly put it on plain water after a flush and keep your fingers crossed.

is that an auto mate?

Yellowing started on lower leaves then spread up, doesn't look like all the mute burn pics I've seen, but I appreciate ur advice, started with 1/4 dose so it wouldn't burn, maybe cuz there is so many ingredients at 1/4 dose??

Yes Barney's farm pineapple express auto fem

wow man, where to start...

Heat, there is WAY to much of it. its dwarfed... Marijuana stops growing at 32 C...

Air exchange. it needs some. Exausting the heat also brings new air into the room.

Nutrients. USE LESS!!! People need to learn, with marijuana Less is MORE when you are learning.

maybe cuz there is so many ingredients at 1/4 dose??

Do some math... 1/4+1/4 = 1/2... 1/2+1/2 = 1.. 1+1=2 so yea... dont use them all at once....

8 nutrients at 1/4 dose is 2 full doses of nutes....

I'm settling on overfert as well.

Judging by the size of the plant to the pot size there must be loads of food in there.

Yep. if the plant hasn't had time to glean the soil for nutes, and he started feeding full dose nutes... that pot will be Jam packed full of stuff....

heres mine mate, they all looked like that.

Get that math logic if I was.adding all apples, but I'm adding apples oranges and strawberries, stupid AN, gotta make things all complicated....
Fan on plants, cab vented.with.4" vortex, temps always been under 32

and these took 14 weeks mate, they prefer a 12/12 cycle, people will slag me for that 2 being, an auto, look at the pics and pm me if you need more advice.

I'll back this up. i know a few strains that like 12/12, its just their thing. people on the forum believe its ethier 18/6 Veg and auto or 12/12 flower... Many of the best growers around have said thats not the best way to do things

That's some good news, kinda, thx! Still think I should do something, flush probably best bet, won't kill her just won't get good yield I suppose. First time at anything is always interesting I suppose.
Ive seen other pics of pineapple express without that much yellowing, I still got 4 weeks left....

Learning is the biggest thing that matters.

Get your seeds for as cheaply as possible for good gene's. Follow other peoples guides and info, and take what you have learned along the way with you.

14 weeks wow, maybe I have more then 4 weeks lol.
Lights were 24 on till about a week ago, 20 on 4 off now. I thought going auto was going to make my grow simpler......guess not if each auto likes different cycles

if you check the cannabia study mate they seem to prefer 14/10, i have never tried this but they seem to make sense.

check my nl out, that was yellow from birth, but that was very cold..... still got 88gs..

Thanks, well another thing to anyone reading this, never start 2 diff strains at diff times, will make fixing one plants problems hard without affecting the other hehe.....doh! Got polarlight#2 next to it 3 weeks behind, just showed sex
