What am I doing wrong? Plants keep Vegging away in flower!!

[Microbeman]

to that I added

1 tablespoon

neem meal
kelp meal
crab meal
blood meal (dr earth's has added probiotics)
glacial rock dust
greensand
DE

2 tablespoon

bone meal (dr earth's has added probiotics)

.5 tablespoon

Weird; I don't think you gave what unit of measure these are added to. On a reammend, I don't think I would add this to more than a cubic foot - 7.5 gallons (liquid measure?); 6.4 (dry gallon?)

I also would not use bloodmeal, nor bone nor sources of calcium/magnesium if already in the original mix. If you want probiotics, EM or EM fermentations are good.

They did take longer than Indica dominant varieties but surprising to me produced ripe flowers.........
I'm not looking to get into a big discussion here but I would like to recommend that you research more (if it even is sativa)

im talking from experience as much as research. experience of trying to grow tropical sativas in often a very small space. (not outdoors under natural light cycles)
25 years ago i cut my growing teeth on sativa bagseed

'sativas' are a very broad term, and what i talk about is not uncommon with some, especially if they have been vegged at 18/6 or whatever. Some can be resistant to flowering until they get to a certain age which is much older than most 'indicas' become mature at. this may not be relevant to the OP but its about the only thing i can think of that could cause the unusual problems that he is talking about (that some of his plants are flowering and some not in the same room). of course they will eventually flower under 12/12 but by that time they may have outgrown an indoor space!

go down and read at the ACE forum who sell a lot of tropical thin leaved sativas and see what advice they give for encouraging flowering indoors under lights.

if i recall correctly Mm, last summer you were suspicious about your sativas being pure or not because they had very wide leaves? also i imagine they were a few months old and got very big before they started flowering? im sure i remember you telling me they had to be chopped back numerous times becuase they grew up to the roof?

im talking about getting them to flower indoors after a few weeks and before they get too huge.

In years previous, I have had success with pure sativa varieties, grown at straight 12 hours of light from beginning to end.

so indoors you gave your pure sativas a different light regime to what you would choose for indicas or hybrids? doesnt that support what i'm saying?

this wouldnt be an option in a room full of mixed strains/cultivars, but yes i agree that vegging under 12/12 would help them flower more quickly

here is a quote from Dubi (ace seeds)

Hello luminous,

......

Haze is hard to grow indoors and we only recommend growing her indoors for pure seed or hybrid seed production but not for a sinsemilla indoor grow.

We don't recommed to flower hazes under classic indoor 12/12 regime.
12/12 is critical photoperiod for many tropical sativas. This means they would grow and grow, elongating internodes to make space for future flowers.

An excessive long 12/12 regime when flowering tropical sativa indoors produces excessive elongation in plants and almost no flower production.

I prefer to veg them with longer cycles (classic 18/6) and start to flower them with 11 (light)/13 (darkness) regime. Then switch to 10/14 after 6-8 weeks of flowering.

Most credible research on equatorial plant species grown under lights uses 12 hour constant to encourage flowering. In a way this supports your point outside of the 10/14 statement. [BTW I was not being specific to the haze]

Yea, the plants did have wider leaflets than anticipated but especially later I was assured of the landrace 'purity' but to be absolutely sure one would need DNA testing.

Yes we did cut them back several times because the growth was so vigorous as to hit the roof of the greenhouse. As stated, I was surprised by the full flowers, especially amidst the squeals from the sidelines annoucing that a [vermi]compost rich soil was much too overpowering for 'delicate' sativas. (;>{)

 

[AloeRuss]

OP - please clear this out for me. You are saying that your plants just slow while being 12/12 or they do not display any signs of being switched?

 

[Guyute54]

I just culled a plant that was in flower for 4 weeks and only had one female preflower showing. While everything else in the room is blooming just fine. The only admendments I added where lime, bone, blood meal. Was very strange I thought maybe it was genetics but maybee I made the soil to hot?

But I did notice I had some gnats in the soil wonder if that could play a roll?

hi Mm, i wasnt being specific to haze either, just used that as a well known example.

Put simply, as far as my knowledge and experience goes, i am very confident that longer dark periods speed up and strengthen the flowering response of 'short day' plants such as cannabis. ( i feel they would be better names as 'long night' plants as it is the dark period that governs the flowering response)
if you ever see any 'credible research' that contradicts that, then i would be interested to see it.

as well as the length of the dark period, age and/or size also have an influence on the onset of flowering, or at least the plant's response to its dark period is generally suppressed until the plant is of a certain age. it seems that tropical sativas, given their native lack of photoperiod variability, are much more influenced by age/size than cultivars from higher lattitudes... so at 12/12 their age/size is a big factor in flowring onset and they can get very big before they flower convincingly, but lengthening the dark period will make the short day response win out over the age/size response.

here are a couple of original haze's that i vegged under 12/12 and flowered under 10/14. i managed to get them to finish in about 12 weeks in one of my smaller 'shoe boxes' that is only about 2ft high. i also used a very light soil which encourages the buds to ripen rather than just keep perpetually growing and throwing new pistils.
i know this isnt the way that you would do it, but it works, no hacking back required.

one pheno at about 8 weeks

another pheno, around 10 weeks

finished nug

 

[Microbeman]

12 days into flowering - natural light. My shoe box. Looks sativa eh?

those amounts are added to 5.5 gallons dry

3 gallons peat 1 gallon castings 1 gallon perilite .5 gallon compost

of that 3 gallons peat i substitute 1 old for 1 new

After some thought and a little more experimentation, I think it might be from my myco teas.
I brew a simple tea, very similar to heisenbergs recipe that can be found easily online.
Just some ewc, molasses and myco's (fungi.com soluble) pretty basic.
But I did notice that when I went to put some in my rdwc waterfarm setup, I poured a cup of tea thru each bucket.
Undiluted, right thru the hydroton into the bottom bucket.
Low and behold a few days later, the three girls I poured the undiluted tea into took off stretching again.
So my best guess is to make sure you dilute your teas.

I'm not 110% sure this is the exact problem I have! I'm sure that old hot recycled mix didn't help things either.
As far as why it did what it did, well that's beyond my area of expertise.
