What food are you using? How much are you feeding them? And are you feeding them with every watering? People are gonna tell you that you don't need to feed young plants but that is WRONG. I feed my plants as soon as they pop up from seed and NEVER have problems and I use promix which is kinda the same as coco (meaning no nutes added) I'm guessing they are probably underfed
Do you use (Fox farms grow big) to add Nitrogen?
If not, what other way, could i add the the Nitrogen? Not Cal/mag i presume

yeah the leafs are warping...im using nutrafield nutes. yeah the coco im using also has no added nutes, and feeding with every watering. i think the strentgh of the solution may be to weak.. the current res mix is 20ml of a and b. 20ml of nf zyme, 20ml cargo boost, and 20ml of fulife. im going to re mix a batch though and put 50ml each of a and b, 30ml of the others. if they are underfed, then that should help fix them yeah??
What do i need to add Nitrogen to the growing medium. Could you tell me the name of a product? Thanks.

hey king grow. there should not be a problem with cal/mag this early on. espec sine i have never run just plain water through my coco to casue lock outs. they are getting brown dead spots on them that just crack and crumble...not on all leafs though. 3 of my seedlings are ok thus far, but the other two have been infected by whatever this is. ill post some pics too

Dont understand the bit where you said you have never passed plain water through the coco? If there is no cal/mag even seedlings will show deficiency its just after a few weeks they tend to require more. I have adjust my water for my coco and soil to 200ppm as stated by canna who make my soil, biocanna terra plus, peat and coir.

so what do you think is causing those spots on the leafs?? i also thought that if you ran plain water through coco with no ferts it causes lock outs....

im not using cana, im using nutrafield line of nutes. a and b base, nf zyme (nitrogen supp) fulife, and cargo boost.

ah ok then, i spoke to my hydro guy, and he didnt think i needed any cal mag when i brought all my nutes...he obv knows what im growing so thats why im a little stumped, also trying to figure out what is causing these leafs to be the way they are

Yer the hydro guys probably right, still look into your nutes on google or other threads see if they used a cal/mag or not. Doubt its pH in fresh soil. Overwatering maybe, you havent added ferts yet or have you? coco needs ferts to start with if its not pre fertilized i think.

yeah i have started ferts already. they get 50ml of a and b, and 30ml for the rest of the supps. all into a 40ltr res that i feed them in a top feed system for around 1-3minutes a day. god dam tubes keep getting blocked though so i might have the hand water. all the run of water goes back to the res. my ph was 6.2. reccomended is 5.8-6.3 so im going to keep it steady and 5.9 hopefully i will see an improvement.
Sorry to be so late getting back to you guys who were all good enough to give me advice, but i have been laid up with my back problems, when it goes properly i am bed bound for a while.
I did not manage to get a ph meter in time, nor do anything other than flush them and then just feed half strength Coco A and Coco B. I left out the booster. I never managed to cure the problem, but i got the plants through to cropping, i got a rather low yield of 30 ounce from six plants. Reduced in quantity, but not in quality, it was still a pretty potent smoke.
I am up and about again now and a friend, who cropped my plants for me, has kicked off another six plants for me.
He cleaned all the big plant pots and trays thoroughly with Jayes fluid and and then thoroughly rinsed them as well. The plants have been in almost a week now and i may have the problem starting a gain, just the odd leaf hear and there have slightly fawn coloured tips, i am just hoping that its the heat thats caused the new plant leaves to turn a fawn colour,as i am having trouble keeping things cool, at times the temp is hitting almost 110 Fahrenheit, 43 Celsius and thats with the front left off the tent so the plants are not getting full light rebound from the front.
I am really struggling to get this temperature down, i guess its just a case of fingers crossed and hope for the best. I will keep posting back as i go along and maybe some one else can glean something from my problems.
Thanks again for all your help and advice, cheers, ralf.

I have had unsolved problems for years sometimes and then i solved them overnight, is just the way the female of the herb species like to screw with your head. That said getting to the cropping part makes a big difference, even if its not great theres always somthing magical about smoking your own homegrown, big two fingers up to the dealers you dont have to pay for weed to for a week or two!lol!
I have just worked through some of my own temp problems so post pics and details again, on my veg chamber i have just installed a big desk fan and leave the door open, keeps it around 22 at max. Always a solution to heat and air exchange unless you live in a very hot area then you need an ac unit. Peace
