I understand the plant uses its stored energy and leaves start to yellow and why but i didnt expect it so soon into flower. Flowering period should be 8-9 weeks and im at 25 days. My first grow looked like my current white widow 7 weeks into flower after a big flush and nothing but water till harvest to force her to use all nutrients available in soil, stems and leaves for a smoother smoke ie no black ash/harshness (this is my understanding of the final flush).
She has stopped vertical growth and is starting to swell so i guess my questions are as follows... although i cant see any roots is there a chance that shes pot bound given the yellowing is so early?

That's one possibility.
Soil pathogens, molds, slimes, nematodes, root aphids, PH, suffocation, etc are others.


If she is pot bound and ALL leaves turn yellow and fall off is she prematurely ready for harvest?

Nope, they use the bud leaf to build flowers.
I have one with all the fans gone and she's mostly cloudy.
Won't be ready for another 2 weeks or so.


Should i monitor trichome colours now? Should i ignore colours etc and wait the recomended 8-9 weeks regardless?
Thankyou for the reply and would appreciate any comments or thoughts people may have on this matter

Yes always watch the trichomes.

Even IBLs will will occasionally turn up phenotypes that have the strain characteristics of either parent and/or grandparent.
And F1s have at least 4 main phenotypes by their nature.
So, use the stated harvest time figure as a general guide.
It's a good bet that your mileage will vary.



"i phoned my hydro shop and was advised that i could give 5-3-3 to up the Nitrogen."

Yes you could. But it would be a bad idea.
Look up "excess nitrogen, in flower".
Hydro store solutions usually have you buying something, yah?

Your leaves do look like low nitrogen, and also like "Iron deficiency anemia".
And the necrosis would seem to indicate several different deficiencies.
Don't chase geese

Keep in mind, that actual deficiencies are fairly rare.
It's more common that the plant simply can not make use of a particular element for any of several reason.
The most common is out-of-range PH.

Your symptoms seem to indicate an uptake problem.
Since your PH is stable, they might indeed have enough root room.
(PH usually varies widely with root bound plants.)

Show us a picture of the new growth and we'll try to see if deficiencies are still indicated.
Meanwhile, I know that you are itching to do something.

So, I suggest that you ad some calmag, or Blackstrap molasses to your next watering.
Is that the fix?
Perhaps not, but it is a good idea in flower, and will do no harm.

Adding nitrogen to a flowering plant will inhibit flowering.
If the plant does take it in, the leaves will turn dark green, krinkle up, and the pistils will be stunted.

Bottom line.

I could be wrong, (it happens), but I will not offer advice that could hose your plants.
No profit in that, for me.


Aloha, grow on.
