They are a lot more yellowish but it's my camera it's poo and you can see how ridged the leaves are and like folded up wards , I don't know for Sertain but think it may be cal mag or something else who knows I've been feeding them 5.5ph up until now I've put to 5.8/5.9ph now also when do I use my pk with them in feeling disheartend as I've been caring for them loads I don't know what to do

So this is my Northern Lights autoflower and she's beginning to twist her little leafs or atleast doing something with her leafs.

Someone mentioned that this could be a watering problem that she is just thirsty. So what do you guys think and what should I do, or maybe do nothing? (I am a unexperienced growe if you haven't noticed already )

Rik ur plant looks fine to me very happy;) good job
Okay nice and good to hear! Thanks beast! So far luck has been on my side and this my first grow with 3 plants 1 auto and the others just normal. The autoflower and 1 normal seed looks beautiful but then there is this one...

420-magazine-mobile48609546.jpg


She has het leafs like that for a few weeks now and she realy doesn't grow a lot. I even think that she has this from the beginning. She is not an autoflower and she is a Durban Poison and I do got her for free when I bought seeds from a Dutch website. But it's still sad to see he this way because I think there is something wrong I hope you guys can help me again and that I can save the little plant!

Cheers!

Some have more developed one has got the little thistle things white hair kinda thing don't know what they are called lol .what about the ridgedness of the leafs the groves are so pronounced I'll up the cal mag dosage tonight's feed and do it at 5,8-6.0 ph
Also my camera doesn't show the yellow ness I know new growth can be a bit yellow but one at back has like yellow ish streaks and patches leafs feel normal maybe heat stress as has hit 32c but I think the light height is fine (I think)

@ Velk, I am not sure exactly what the over all issues are that are causing the problems you are haveing with your grow to date, however vegging or flowering at 80/90 RH and at 30 c seems to me to be a big part of the problem. i am a newbie so take what I say with a mall grain of salt :). I would think at these RH levels that it is like showering your plants with a constanct mist of water; I have read that your plants can take in moisture from leaves or their roots and will not do both if there is an overall availability of moisture. Having said this I did read an interesting clip on water and heat stress affects on plants,

"When the plants water intake from the roots drops below a certain threshold, the plant cannot maintain proper fluid pressure, and to preserve it from wilting a chemical called Abscisic Acid (ABA) is created that signals a number of responses, most important of which is it signals the closing of the stomata (small pores in the leaf) to prevent further water transpiration. The upside is the plant doesn’t wilt or fall over. The downside is the plant stops taking in CO2 which enters the plant through those stomata. With the closing of the stomata, the plant effectively stops growing. A similar effect happens with high temperature stress,

So is it possible that the plants are not taking in any water from the roots no matter the moisture present because the leaves are constantly being drenched by RH levels and this is causing the closing of the stomata? PH would cause deficientcies but water stress and heat stress are worse (30C is too high from what I read - 23C top of canopy is recommended).

If it were me I would do a 2:1 water volume flush on all plants than leave alone for 2-3 days until soil starts to dry out, do not worry about PH level, immediately install an air conditioner or suck air from outside if cool enough - drop the templerature to around 22-23c, install a dehumidifier and aim for a 40-50 RH level. I am also guessing the CO2 levels in this room are pretty low with the RH and heat levels you are running.

My plants seem to be doing fine in main grow room but in the mother room the same plant that is looking great @50% RH and 23C and good intake/outake of air exchange and artificial winds, starts to look sick within one day of being blasted with a temperature of 30+C and lack of air exchange; RH is 40 in this room so it is just a heat/air exchange stress issue.

Again I just a newbie, trying to think outside the box, good luck!

It's not constantly at 30 but it's been touching up to that the rh was mad high normally it's 55-65 it's gone crazy and thanks for that info that's handy I'm saving that to the scrap book .. And only problem is I'm using coco so I have to water every day unfortunately normally it sits around 25c and nice rh but it's just went crazy all of a sudden I don't understand it man it's frustrating and I have the flap open as much as I can gonna put my other fan in there help with air flow

When the temperature outside goes above 0 c, my room goes up to like 29+c, this is rare this time of year. Two 6 inch intake fans and the light heat from the 4 HPS's is crazy. I will have to double intake in summer and add air conditioning, maybe leds too.

Velk they look good to me I also get the odd yellowing and thinning of leaves in the bushier inside of the plant I just pull it off it's always been ok
