Just take a guess

[Gquebed]

Two pics from two seperate plants vegging out as potential moms. Black Ice and northern lights. Under cobs in promix.

Take a guess at what problem the leafs are showing just by looking?

 

[Gquebed]

Potassium and sulphur def?

Bottum pic looks like calcium and magnesium, any fungus gnats you see

 

[Discreetdigrowman]

Definetly calcium will make the growth twisted, lack of calcium i meen

I would guess phosphorus deficiency in top pic and calcium def in bottom pic.

I have pretty hard water...lots of calcium. 240 ppm on its own. But ive supplemented with cal mag up to 450 between feedings. (In veg i water feed water). Maybe not enough still...

Dialling in the nute needs for cobs has been a challenge...

promix tends to run real low ph if its below 5.5 calcium cannot be absorbed, i have trouble myself dialing in my girls under my quantums and hid leds in promix im adding dolomite lime try to bring up my ph

Hmmm... you mean even if i ph my nutes up to 6.5ish .... you say the promix is pulling it down somehow?

I never had any ph problems with hps... or nute probs...

Thats why im struggling now... never had to trouble shoot before so i suck at it...

What kind of pots im in smart pots and my theory is they dry so fast even at correct ph it might go down enough at the root base to miss calcium and magneseum phosphorus

I've had problems in peat bases like pro mix.

Wierd yellowing and twisting.

I got mad and threw a she bale in my compost pile. I bought 4- 4 cubic foot bales and one was bad.

It happens. That was with the addition of my nor.am organic amendments.

 

[Discreetdigrowman]

Yeah could be a bad bale

 

[Gquebed]

I dunno...third run with the cobs...all the samish. Im dialling in....slowly....very slowly...lol

What ive been told is that they need more nutes with cobs.
Okay? How much more?
I think i under did it. Then over did it. Then under did it....with my current run which is just a mom hunt rigjt now. So no biggie... just like to nail it down before i clone.
