Growing help

[Pretendxo]

Hello! This is my first ever attempt at growing. I recently switched my seedling to a bigger pot but the leaves on the bottom are starting to show these spots (as pictured). From research, it looks like it could be nutrients (potassium?) But I'm not sure. I just ordered PH strip testers and got some nutrient suppliements as well. Any insight to what this might be would be helpful!!

What kind of soil is that?

Looks to me like a pH lockout situation.

You will need to pH your input. Since you are in coco by the looks of it, a pH of 6.0 is where it's at in veg.

Test what you have been gving it. I am guessing it is way too high but test and correct it. Correcting it usually means going slightly either side of the 6 to bring it back to where it needs to be.

Agreed although with coco Mag is always an issue so it might be that also. Judging from your pictures you need to go to the tutorial section of the site and read up on proper watering practices. Could be your just not giving the plant enough water.

I'm guessing boron so guessing too high. Cal/Mag if it's too low or even good I guess.
