I can’t figure out what’s going on

[MegaClutch]

So I have 2 strains and only 1 of the strains is doing this. I’m doing a 4x4 rockwhool on a uni slab.

All of the plants of same strain an how many of that same strain are doing this? You run it before? Could be light distance, nute uptake? They don't look like there's much wrong other than Ph off. Are the rockwool cubes feeling real damp a day after watering on them? Are they on a auto water setup?

 

[MegaClutch]

just this strain has like 4 or 5 plants with this problem. Lights are far enough. Rockwhool is heavy because this started after the transplant. And I’ve over watered once since the transplant and yes I have a drip system. I was thinking ph problem too but won’t it effect my whole room ?

I was thinking a bit much light early on, over water, and early days of a mag def.

 

[9fingerleafs]

Yeah. Kinda looks like it could be a mag hungry strain, the overwatering could have impaired mag uptake so maybe try a bit of calmag and if it doesn't respond adjust the watering cycles

 

[Rootsruler]

Foliar mag application should give you a quick answer........

That's a good idea...
