thanks i have to think outside the box a little bit. i don’t have the best setup but i’m learning and the curve is fierce!


If you’re in coco I would say your ph is too high. I’m in straight coco and i ph to 5.8-6.0. Happy growing!

I will also add ive never used the medium you stated


You have 2 x 600w lights going one high pressure sodium and a metal halide?

I’m not the light guy but that seems alot.

I built a box 10x8x10 I have added a picture so you can visualize it.

Only on two of them you found these strange symptoms?

Do you know how to grow in the royal gold coco coir?

If I’m reading it right on their page… You are meant to feed them?

Yes only on 2 of them. I have been reading and i’m almost positive i should have a reservoir of some kind and a drip system connected to a pump to either constantly feed or drip for a certain amount of time, a few times a day. Would that make the leaves look marble like?

I think the leaves are pointing to being underfed. The coco based product you have needs feeding with every watering, cal-mag with every watering, water until runoff every time, and watering often, as often as several times a day using your drip system.


I agree with c michgrower you are using coco w. Pearlite if you want to auto feed or hand water doesn’t matter but nutrients almost every watering and cal mag you have good coco but coco doesn’t feed plants it’s a hybrid Hydro system


Listen to these two guys above… :point_up_2: they seem to know what they are talking about…

That’s nothing to worry about. I’ve had several plants grow with that weird pattern on the leaves.
I’ve got it boiled down to bad genetics or old seeds.
As long as everything else is healthy I’d ignore it completely.

See below.


Did they grow like that and did they stay like that or recovered?

it grew fine, but the crazy pattern continued on the fan leaves throughout the grow.

Looks like variegated leaves.


I’m seeing the same. Would definitely lower the ph to hydro/coco levels before that does become an issue.
