I recently bought a clone from a dispensary on grape st. in San Diego.
Being a first time grower, I was not informed on how to identify powder mildew or spider mites.
I bought it on monday, its now friday morning.
I noticed the white powder at the base of the stem when i bought it and thought it may have been rooting hormones or somthing.
I noticed what looked like crystals forming on the plant's leaves two days ago and knowing that its only three weeks old and in veg, i knew that wasnt right.
It turns out that the dispensary sold me a plant with mildew already growing on it.
And upon further investigation, I found that i had a spider mite issue as well.

In the first two days i had an issue with yellowing leaves and i backed off the lights a bit and switched to distilled water and misted once a day which fixed that problem. I'm curious as to what dispensary because I think we may be victims of the same crime.
