Harvest & Curing almost ready to harvest - newby?!

[crab]

hi all,
these are my girls, behind, left: barneys sin trabajo, right: barneys little cheese; front, left: dinafem critical 2.0, right: delicious cheese candy.
all under 22/2 since 2nd june, except little cheese that took one more week to germinate.
light: cfl 150W + 2 grow led 10W each added 2 weeks ago.
the room is very little 80x90X35cm.
they are very stretched even if i kept them always as possible near the light.
the pots are little because the plan A was taking 2 of them outdoor.
watered with water and lemon juice with ph around 6.
3 week ago i started giving them atami "bcuzz A+B" and then ripen "late flowering nutrient" in little doses once a week. instead of that leaves seem suffer burning.
the heat is a problem: the home made air extractor can't remove all warm air on top and when i added leds, temp grew.
critical and sin trabajo seems to be almost ready, the other two not.
the question are:
is it time to harvest ciritcal and sin trabajo? i would keep them a bit more to increase cbd levels.
why are all so under productive and so stretched?
thanks all for help!

Your girls are stretched could be from several things.Not enough lights probably the main reason, even if you have them close you need more wattage to keep them from stretching.Also could be small pots,not enough nitrogen,not large enough dosage of nutes,ph not correct.You should wait until most if not all your pistols turn brown,and also check your trychomes to see where there at.

these are taken 2 days ago, 10weeks since birth
the temp is a bit high, but i cant do anything now... 91°F
could be ready?

Nice and frosty .... If they were mine I'd give them another 2 weeks, plus all the fresh air you can blow their way ... you can cut the hours of light down if that helps temperatures ...

I'd like to chop them when they will ambered to obtain more cbd. but i don't want to overpass harvesting window (in that case what happens to the harvest?).
all the time i've taken 22/2. which shedule do you advice? consider that the 2 girls divide the room with other 2 a little bit late, as you can see in prev photos.
I'll add another fan into the room, the only one it's too weak and extractor only move around 40mc/h, but it's very quiet!

If a plant must endure high heat then it likes lots of fresh air ... they can grow outdoors at higher temps than indoors because of all the fresh air ... I have a hot closet grow going ... currently light schedule is 20/4 down from 24/0 due to heat concerns ... most new growers harvest too early ... if for lack of meds you can always cut a bud or two early and let the rest mature ... your plants look healthy but they look like they are 2-3 weeks from being done ... plants seldom finish on time unless they have a near perfect environment ... I'd just keep doing what you're doing cause it's working ... maybe one more feed and then switch to plain water for 2 weeks for the cleanse .... overshooting the harvest window almost never happens .... when your plants look like they are done growing and the pistils have all turned brown and the fan leaves are shriveled up ... that's about the end of the harvest window ...
