She is a 15 day old Think Diff.

Last week I found a spider mite and foliar sprayed with cayenne/garlic/distilled water....haven't seen another one.

I did notice some light patchy spots on leaves forming and tired of trying to diagnose since I have never grown before. Roots look good, no rot. SO frustrated.

Any and all help is appreciated. I have read every single diagnoses, defic, etc on this forum...over last 5 days. Still not sure what it is :Stones slap:

Did this start after you sprayed?

Looks like you did some damage with your spray on those two leaves.Just spray with plain water to rinse them off and see if it continues. Next time use some organic bug spray no more homemade spray.::karma Cloud:
