Hey, just wondering if anyone could chime in and help me with what looks like over watered or under watered. Plants are 33 days old, under 750watt air cooled hood temps are 74f

750watt air cooled hood temps are 74f

So these are cold 74F = 22c !!................... thats lights on !! you need 23c lights out to keep the root ball temp up at 22c minimum so the plant can take up the nutes in tropical conditions it is programmed for !!.....

At this age you should be feeding an Ec of around 0.5 to 0.7 minimum, at Ph 6.5, they look just pre flower, so 35 days old ??...................... up the feed, and the temperature of the rootball................ the sack pots loose twice the water compared to closed in plastic pots............ extra water is lost to high transpiration through the pot sack cloth sides, by capillary action................ so water well, as water will transevap before plant can use reserves stored............... i water 2ltrs in a plastic pot, and 5ltrs in an airpot for same results !!

low grow medium temperatures lead to acidity in the grow medium is wet and cold !! = not good, as when Ph drops due to acidic cold wet soils nutes drop out of availability;..... Phos and Mag begin to drop out of availability at Ph 5.7 or below............ ALR

Solid Solid advice my friend, since reading your reply ive since upped the temperature sitting around 78-80 and the ladies have been doing very well since, seeing proper drying cycles of the fabric pot also, added and tower oscillating fan which has helped tremendously. Thanks for the reply much appreciated and was able to learn alot of new information
 
Solid Solid advice my friend, since reading your reply

Thanks, I did on occasion, learn the hard way also, however, the thought of other suffering such troublesome anxiety with growing our treats................. i dont hesitate to head of issues at the pass, when i see them hovering around !!..............

The low humidity could be causing you to use more than your giving.

The vapor pressure differential, UN-beknown to a few, can and will play a part in the final yeilds......... these are the target ranges, we need to try to remain within, sorta like a BMI chart for cannabis breathing !!...........we prefer to remain in the VPD "Green Zone" for obvious reasons !!.................... "Stoma" do not like to breath hard.........;),

Accordingly, vital energy is wasted doing so,................ if you have ever trekked in a low oxygen atmosphere, you will have simpathy for the stoma sit rep.... 'Remember, (All cannabis Strains Are; "Anemophylic" as almost all gymnosperms are "Anemophilous", as are many plants in the order Poales , including grasses , … of course !!

:yeahthat: Thanks ALR, solid advise as always!

Not a problem Waira, i have been storing a few thing, you have helped people with also Waira mate,........ a couple of thread roaming "Canna Altruist's" UN-stoppable ;) Altruism is the principle and moral practice of concern for happiness of other human beings, trying to grow top top draw "Cannabisss", resulting in a "High" quality of life and vapes ! both material and spiritual. It is a traditional virtue............... continue your good work my man.... ALR

Yep, &
I would also suggest taking your humidity at different heights, I have 3 gauges, 1 @ the catch pan, 1 @ canopy and 1 @ light level.
Temps will vary by 6 degrees and humidity by up to 15% between them. I use canopy level for calculating VPD (thinking here is we are talking stoma...)
Amazing the difference it can make.

3 edits to get this right... time to smoke.

:passit: Cheers to that mate! My journey here has been amazing, trying to climb that learning curve rapidly,... I have lots of plant experience in general, working at regular retail nurseries, hobby plants (carnivores, cactus/succulents, orchids), then at a friends species specialty orchid greenhouses... but my cannabis growing is young still, only really had my first real grow in '12, joined here in '13... I had lots of help, a couple great mentors, who got me helping other mates trouble-shoot as I learned too, then next thing I know I'm "working" here! :biggrin:... been doing this for nearly 4 years, but my limited experience in other grow modalities has made it tough at times,... no hydro runs, or coco/soilless,.. always been a Sun and soil guy mainly! Diagnostics is a whole different game, a deeper well than what I realized when I jumped in! :help: ... it's difficult and time consuming, small wonder there are so few Staff that even delve, much less take on as main duties here...:deadhorse: :haha: ... I'm learning as i go too, sometimes vicariously! If I'm not sure, I try to call in those who know better, more experience.... I hate "arm chair" experts, and try hard to avoid being one! :biggrin: ... last thing I ever want to do is ill-advise somebody and cause their grow to fail :yoinks: :baghead: .... So, I'll be going to school on your advises as well mate, thank you again!
