Weird

[Macster2]

Strange,out of 6 plants (I've not been able to sex yet) I've got this one, I've treated them all the same but this one has yellow in the middle, any idea why?

Well i will get a pic of one of my plants it is the only one with yellow new growth. I was worried too but it changes to green once the new leaves are developed. Its not a problem I dont think because i fed mine plenty npk and trace elements to solve it and it remained yellow. I would say its just a genetic trait.

Keep an eye on it and let me know if it gets worse or the leaves develop and turn green

Here check this photo out...i believe oyu either got N def. or a nute lock out...but check this photo out and this is a pictue of N def..... i think it matches up perfectly

Well goto the N Def. part in the site and it has pics of MJ plpants that arent getting enough nirogen.

mad heat stress9curled tips0 so its probably a swing in temps from hella hot in the day to just 'cool' at night... probably compounded with a mag/n/ca def.. she looks like shes need more food and less heat.

Tks guys, I'll ph test my water again and move the light up a touch.It might be a genetic trait as the others are feed the same and are equal distance from the light and I've notice some heat stress but it's the weird yellowing I'm concerned about

your plants have problems from the looks of things but light green new growth isn't necessarily bad.
it happened to me and it was just that the plant was growing too fast.
after a few days they get "normal" green.

Super heat stress and Fe lockout.
Check your soil runoff pH, control your temps, make sure that your fert contains micronutes.

i agree with stinkyattic ,but filling out the sick plant form will help diagnose 100% accuratly

Thats a severe nutrient based and/or a severe pH issue, Teruso is correct with newest growth sometimes being yellowish, but your whole plant has it along with chlorosis of the leaves. Have you given it any trace nutrients, which should correct the chlorosis aspect at least. Id guess you gave it too much nutrients, thus the reason the oldest leaves are yellowing and dying off. I also notice the leaves of your other plants in the pic clearly have too much N if not other issues as well. With out knowing more details I couldnt help you anymore then what Ive already typed. Good luck though!

Heat stress and it looks so bad that I would think your root zone is boilin them alive and doin all kinds of crazy shit with your nutes and causing severe lockout
