2 weeks flowering problem

[blanchdave]

This plant is losing leaves fast...check the link in my Sig for pics of her when she was more healthy....Heres the details of the grow.

Growing in 70% soil, 30% perlite mix.....Vegged using 4x 36w 4ft fluro tubes,, 400w Hps for flowering.
Canna Bio Vega 100% organic (3.5-1.0-5.5)
Canna Bio flores 100% organic (2.5-2.0-5.0)

5th Nov: Sprouted
4th Jan: Topped
12th Jan: Re-potted
22nd Jan: Switched to 12/12
2nd Feb: First flowers appearing (last feed using Vega) soil run-off 6.5ph
3rd Feb: LST top of plant
7th Feb: Start using Flores nute's
11th Feb:Feed using flores - yellowing is half-way up plant
17th Feb:Fed using Flores - soil runoff = 6.5

I check ph using both test strips and a digital ph meter pen,, so the ph readings are accurate.
Temps During lights-on are about 70-75F...lights-out = 65

Any ideas whats gone wrong ?
Should i flush ?

Thanks Folks !!!

could just be from lack of light to the lower portions cause you did let that stretch a bit too much should have kept it shorter, had the right idea just didn't do it soon enough to make a real difference.

Thanks for the info.... if this is the case,, then what does it mean for the plant ?
Will it completely die ?

It could be me, but I think that plant is just SCREAMING!!!!! for nutes.
If the plant can't uptake enough nutes for bud formation, it will rob the leaves of everything they've got to construct your precious ganja!

The Canna bio flores says on the bottle to mix 40ml to 10Litres of water......at the minute i mix 4ml with 2litres, which is 50% stated dosage.....what do u guys recommend i up this to ?

[blanchdave]

any1 ?

[curtropolis420]

this isn't that hard it'll be ok grab a bag of earthworm castings (looks low on n) stick 3 or 4 6500k cfl bulbs around the base of your plant will help construct sugars and more resiny buds and give it more nutrients!

Hmmm let's see : you give the plant 1/2 of the recommended nutes, someone on the forum suggests to feed your plant more.

What does one do then?
Choices, choices!

that plant is hungry. you underfed it through veg and it's showing now in flower. obviously nitrogen starved, too soon. i'd feed, increasing strength by at least 25%. i might even feed some veg food.

What is in your soil mix? Soil means what? Did you mix in some lime?

The first thing I would suggest is to check all ph factors.. By the time the girls get to mid flower many things could have changed, including the ph. Check the runoff, the medium and the nute mix.. If the ph is too low or high then you can get lock out of nutes.

The reason why i asked again is because you said the plant was "Screaming for Nutes"......All i wanted to know was do u mean give it nutes more regularly or at a higher dosage !!!

Thanks to the rest of u guys for the Helpful comments.

As the others said it needs something high in nitrogen because it has classic nitro deficiency. Give it at half strength though because flip flopping back and forth from bloom to veg nutes can cause stress even though it is completely necessary to do with all the strains I have ever grown.

[Durban_Guy]

flowering nutrients lack in nitrogen because the need of new leaves is not needed. Its usually natural for the bigger fan leaves to go yellow and maybe fall off. If you using a 400w hps so flower this puppy, it aint a light problem. i think increase ur nutrients a tiny bit aswell.

woops sorry bout that

Let me be of some more help : assuming you are watering properly now, that is to say not to much and not to little, logic dictates that the only option you have is too increase the dosage.

The "Screaming for Nutes" part was to illustrate the neediness of your plant, not to emphasize on your lack of experience.
Most people start asking questions after their first set of leaves go yellow.

Please, think first, respond later.
