Help, my girls are turning to barf!

[Weedgrodamus]

I have been struggling with my White Widows, they are 30 days into flower and it looks like potassium deficiency, they started showing these signs about 20 days ago.

I have been scrupulous with the nutes using Canna Coco 2 part and Cal-Mag supplements plus a teaspoon of organic molasses per gallon. Ph is 6 and I made sure the pots were dry before last watering to make sure I wasn't over watering, despite that it seems the yellowing and burned leaves are spreading. Also the small flowers seem to have a powder already and the smell has changed, the girls were a bit skunky but now it almost smells like barf. I am really needing some advice.

What's your medium

how old is plant altogether...

 

[Weedgrodamus]

No Title

The Girls are 4.5 Months old in Coco/Perlite 70/30 mix.

I just defoliated.

My leaves are turning yellow and I have been so careful not to over water or under water this is my second grow to :dead: So many things can turn a leaf yellow its mind bending .Are you using super soil you don't say.

 

[Weedgrodamus]

I'm using Coco coir and Perlite.

What's your feeding/water schedule

 

[Weedgrodamus]

I feed whenever pot is dry which is every 2-3 days.

 

[Green75]

Do you ever give plain ph water

 

[Weedgrodamus]

Yes, I do a flush of distilled water every 2 weeks.

 

[Green75]

Try doing that after every two feedings...

fan leaves die off first in bloom we stop giving the plant Nitrogen. so the leaves die off . trim off the dying stuff . your powder on the other hand could be powdery mildew . spray with neem oil every 10 days. use a garden sprayer . I get my neem oil in concentrated form from Lowes its cheaper the a grow store. just reread your post around the flower will usually be trichromes it kinda looks like snow but if its on fan leaves and you can wipe it off then spray. neem oil can be sprayed right up until harvest and the girls love it

My first guess is severe nuet burn. I have been growing in coco as well, and I alternate plain PH'd water every other feeding now as I was getting PH problems from salt build up (using GH Flora Trio).

 

[Weedgrodamus]

Neem oil sounds good, powder was only by flowers though, and it was on all flowers and no leaves, I'm thinking maybe that why they call them "White" Widows.
Still Neem sounds like a good precaution.

 

[Weedgrodamus]

So no Nutes 2nd or 3rd other feeding?

 

[StoneyTony]

That should do the trick. Also, Nebula posted a good watering schedule for coco: http://www.growweedeasy.com/sites/growweedeasy.com/files/coco-coir-flora-series-schedule.pdf

Thats the schedule I follow w coco to, and havent had any nute issues yet thankfully.

Good luck, weedgrodamus: nobody wants weed that smells like barf!!! Keep us posted!!!

Its been 5 days since I switched to the new watering regimen and defoliated, and the girls are still looking poorly but are not worsening, and smelling barfly.
I'm going to open the tent and blow fresh air on them for awhile everyday now that weather is nice. I guessing the leaf discoloration may never recover, i'm just hoping the new leaves aren't yellow also.

I am a uber driver, and as such I am familiar with the smell of vomit. TAKE MY WORD ON IT YOU GET USED TO IT!

No worries. Damaged leaves won't return in color. Wait until you get some new growth (unless you have plenty other leaves now) and cut the bad leaves off.
