Another leaf diagnosis request.

This plant is only about three weeks old. Is it just time to start feeding? Coco coir, perlite, and potting soil. Watering when dry, about every other day. LED lights (Viparspectra). Strain is G13xGenius from Bros. Grimm, otherwise very vigorous.

feeeeeed meeeeee

Low pH at the rootzone.

Don't mix coco and soil. They are different animals.

I was hoping to do an "organic" grow. I'm about to transplant into super soil (Maine Coastal Platinum) but no roots are poking out of the bottom of the cup, so I'm thinking about General Hydroponics MaxiGro, but mixed 1/2 teaspoons to a gallon, not the one or two teaspoons they recommend. I do check the pH of the water (low sixes) which comes from a well and gets "softened" because of high iron and manganese.

It’s possible that the soil makes the water too acidic. I would recommend immediate transplanting to coco coir to a larger pot. Water flush with PH of 7 then let it dry a bit a watch the growth. Your leaf structure indicates that plant is not observing nutes.

I just transplanted to a 5G fabric pot full of Michigan Mix. Except for those lower leaves, plant looks good.

Upper leafs have smaller problem since they are smaller. The plant moves some nutes up from lower leaves that’s why those start to look worse
