Leaves are thick and outlined dark green?

[funkytownbiguu]

Does anyone have any experience with this? The leaves are like thick and full but they're ridged? I dont know how to describe it but it's like they've gone 3 dimensional. And then obviously lighter in the middle and dark in the veins and outside. Thought it might be magnesium but I don't want to add anything until I feel more comfortable about my diagnosis. I'm running crop salts.PH between 5.8-6.2. +/-1500 EC . The crazy thing is I have another plant in coco doing the exact same thing on a much larger scale. Same strain. Ive got this one in this shared tub which I now see is probably not best for everyone involved so I'm going to move into a solo dwc but I still need it correct her deficiency / toxicity. From now on if they're going to be sharing a tub they're going to be the same strain.

g'morning sir, and welcome to the fam.

i'm growing right now in a homemade mash up between dw and rockwool uni-slab

w/ general hydroponics 6 part aggressive. (are you sure you're running 1500 ec & not

ppm?) 1500ppm is my top limit, above that tips can start burning (depending on cultivar)

1500 is imho way to high for that young of a plant, should be around 600-800 ppm.

the beauty of hydro is if things start going south, all you have to do is drain the reservoir,

clean it out & flush the shit out it for at least 1 hour w/ plain water at 5.8-62. after

that, mix a fresh batch @ 1/2 strength or around 400-600ppm for plants that size, again

imho. very important, always mix calmag in plain water first, (unless using silica, if thats

the case, silica must be added 1st,then calmag, then base, then whatever else you're

putting in it. also, it looks like your feeder tube could be closer. my plant is 40 days old

from seed. hope it helps or gives you ideas

peace
