Need urgent help!!

I NEED HELP WITH 2 PLANTS, IM NOT SURE WHAT TO DO NEXT WITH THEM TO BE HONEST AND NEED AN EXPERIENCED GROWERS HELP TO IDENTIFY PROBLEMS WITH THE PLANTS THROUGH PICTURES UNDERNEATH!!
( IF MORE PICTURES OR SPECIFIC PICTURES ARE NEEDED PLEASE COMMENT AND I WILL PROVIDE THEM TO YOU )!!!!!
BOTH ARE: Joint Dr's Lowryder diesel rider autoflower and feminized!!

ladies look underwatered-heat stressed.

The yellowing is not an issue on that 1 fan leaf...

I would lollipop them but.. each grower has their own prefs..

yep lolipop/prun the bottom 1/4 .. all that tutch or is near to touch the soil ..

and yea .. what temps are you running ? might be a bit to high (like the rest of us) might make your water evaporate quicker so your girls go tirsty ?

I need some data to help you out. EC? Nutes you are using? pH ? Last water? type of water/ treatment? Temperature? Soil or coco looks dry. Your lower leaves look like cal mag deficiency. The rest of your plant is having problems transpiring (sweating)- hence the leaf margin cupping. Potassium is responsible fr regulating stomata (pores on underside of leaf.) In soil its best absorbed around 6.4 pH. At you stage in plants growth you should have about Nitrogen - 100 ppm Phosphorous - 60 PPM, Potassium (120 ppm- up it because it needs it). Iron- 4 ppmgradually raise the levels about 50 ppm every other water. Start with high potassium feed. Keep soil moist about a quarter inch down. Don't give up man!

Remember to just raise it gradually! Your plant is stressed you want mostly water first. If you have a root innoculant like ZHO/ aqushield use that with every other water and a small amount of molasses to help them breed (about 1/2 TBSP per gallon. Hope that helps.

Ok so Lollipopping is just taking away the bottom 4-6 branches?,
I usually water when the soil is dry on top and lightly moist about an inch below the top of the soil.
cheers for the help m8!

Ok i see, whats the tutch sorry?,
Actually my temps are too high i know that they are running at 32 at mo but they sometimes go right up to 39!, I have tried controlling the temp but having no joy!, I even stuck more fans in to help circulation but in the end the temps just kept rising, i was also running an in-line extractor with carbon filter, but it seemed to be useless so i now use it for an internal fan, with an oscilator fan inside running all the time to keep plants and soil cool.

Also I dont give them much water when i do water them, i give them about 1000ML(1Litre), simply because I dont want to give it too much! but im afraid I may be giving too little now!

Ok, I was actually just growing them with no nutes at all as I want it as clean as possible when its ready to smoke, but recently ive been feeding each plant with 5ml of tomato feed diluted in 1litre of water, my last water was yesterday morning, also i when i water in the mornings i give a touch of mist too. the water is pretty good in my area so its just plain tap water, temps are way high ranging from 30-39 degrees!, the soil is biobizz all mix, im sure the tomato feed has all the nutrients it needs but im not sure im giving it enough?, if im honest with you i dont really understand the terms for the nitrogen etc.. like the PPM? and i wouldnt know which product to get for it?
Im certainly not giving up ill do anything to make the babys work!

THANKS FOR ALL THE HELP M8 ITS MUCH APPRECIATED!

^^^^^^^^^^ Definitely heat stress and, as noted above, the beginnings of a cal/mag deficiency. Fixing your high temp problem could very well correct the rest of the problems with the exception of the cal/mag deficiency.

Also is there a certain way to cut them off?

Ok i see thanks m8, do you have any suggestions on lowering temps as my solutions clearly dont work lol?

Managed to get temps down to 28 degrees celcius now!!

You have heat stress going on. When your leaves form a taco that is the tell tale sign. You also appear to have underwatering issues the leaes are drooping as well.

DO not use straight tap. For one thing, your municipality most likely uses CHLORMAINES. These are nasty, nasty. Even a FEW PPM can prevent seedling germination, prevent root growth, and it messes with the plants hormones sometimes causing hermaphrodites. How do I know this?? For 8 months I had failed grow after failed grow, I was using an RO filter with 7 uS (3 ppm coming out) so I thought the water wasn't the problem. I had the EXACT same symptoms you have. Strange nute lockout issues, droopiness, etc... RO filter does NOT remove chloramines. UV filters can remove them, but they have to be medium pressure UVA-UVB-UVC (200-400 nM wavelength I believe). What I do now is use API tap water conditioner which neutralizes the chloramines, but leaves behind some Tetra Sodium thiosulfate. The tetra sodium is good as it acts as a chelator, isolating the metal ions from reacting with anything until they hit the roots. The sulphur does not affect the plants as long as you have a decent amount of potassium. Sodium displaces potassium so you just have to up the amount to compensate. DO NOT TRUST TAP WATER, regardless of what your water report says. DON"T mist them with tap water either, it will clog the pores. The only thing you should mist with is plain distilled. It may be to late to recover the calmag deficiency. Its mostly a non-mobile nutrient and once it starts it tends to get worse no matter what you do, but you can add epsom salts or any calmag enhancer to limit damage. The main thing youhave to worry about is flushing this shit out of those chlormaines/ tap water. Do a plain distilled flush at least 5 X container volume. Plant will exhibit overwatering for a few days. Add 1 tbps of mollasses to each 2 gallons of distilled to You can also use crushed up vitamin C to remove chloramines. DO NOT LET ANYONE TELL YOU CHLORAMINES ARE FINE. Besides, you cannot be sure the exact ppm that comes out of YOUR faucet..

Thanks for taking your time to explain and help me mate im going to take your advice and try it out, At the moment i have already lowered temps down to 27 now and also trimmed off a few lower levels of leaf as recommended to by another experienced member, plants looking great already cant believe the difference it makes within a few hours!!

Thanks again!!
