Yellow/Brown Leaves

Anyone know whats going on with these leaves on one of my Skywalker plants? its only the one set of leaves, 4th node up. about 4 weeks from seed now and they seem to be turning a yellow/brown color from the inside out. i havent given them any nutes yet so it cant be that. yet i cant seem to identify it with any of the deficiencies in Cervantes grow bible... any ideas?

dont know what it is. if it dont get worse then dont worry man.

cold temps

really? i dont think so... temps have been stable around 75-80. they do seem to be getting worse though thats the thing. theyre starting to get crispy and fold in half...

what soil mix are u using?
r u using ro water?
is the water ph'd?

I would guess MG deficiency, but I could be wrong.

Very well could be it. Any well rounded nute should take care of it.

what type of soil bra? what's your humidity?

fox farm ocean forest soil mixed with 25% perlite. no RO water ph 6.2. humidity 40%-50% temps 75-80. i think it must be Mg deficiency then since one of my other plants had that too from the tap water it just looks different than this one and also cleared up pretty quick with some salt water. this one just seems to be getting worse though...

i wish i could make up something u are doing wrong, but i cant think of what it could be. from my point of view u know what u are doin. all i know about skywalker is the blueberry half likes to eat, i don't know shit about the mazar half.. just going by what i know i would guess deficiency, but just a guess. GL

yeah thats all ive been doing is guessing haha. been watering with extra salt water and spraying the leaves with it hopefully that helps. what do you mean by the bb half likes to eat you think i should be feeding with nutes??

At this time of the growth i would be using 25% of nutes. If they can handel it i start to increase the dosage, also depending on how she looks.

It has been much colder in the last few days, but the flowering room was at ~60F when the lights came on both days and it hasn't dropped below 60F.The plants have begun to yellow and curl over similar to over nurtient, but I am not sure and am wondering about my mix...

I have now switched to a 6-30-30 Bloomit and I am going to use the ratio of 3 and 1/2 teaspoons per 5 gallons of water. I give under the recommended amount of 1 teaspoon per gallon and I water every 3-4 days as needed. I only flush with strait water for the last 2 weeks.

Is it ok to use this water mix every watering?
Should I switch to every other watering adding the nutrients?

The plants have also been sprayed with "Spray and Grow" and I wanted to know if that was ok 2 times a day? Once about 1 hr into the lights turning on and 1 hr before the lights go out for the day.

Any help would be appreciated.
Pics are attached...

thanks,

the leaves are supposed to start turning yellow and curl during flowering man thats perfectly normal... i wouldnt recommend spraying them with anything during flowering either youre just asking for some mold

I would also not spray anything during flowering aswell, only if you got mites spray during flowering, you run the risk of having shit tasting buds at the end...It looks like too much nutes, but you can always run tests on a few plants to see how they react.

Its the soil your using mate....that soil is known to be a little on the hot side man, u wanted to mix at least 50/50 with something neutral.....your best bet is probably take em out, remix and repot

What I would use is 25% ocean forest, 25% light warrior, 25% coconut fiber, and 25% perlite, something to that effect. im no pro, im just telling you what I heard....look up Ohsogreen's posts, he talks about it somewhere in organic forum, i remember reading it just cant find it

really i have 13 plants in that mix right now and they all look great besides this one haha. its actually starting to clear up a bit i started them on some nutes the other day
