Good day,
I’m a first time grower - about 9 weeks into growing the Beginner Mixpack autoflower - White Widow, AK-47, and Bubble Gum.
I’ve got some plants with yellow spots and leaf edges - see pics. I’ve been using Bergman’s plant food fertilizer to water each time, following instructions. Began growing inside and switched to an outdoor greenhouse about a week ago; however, the spots/edges began before moving them outdoors. They’re growing in Miracle-Gro Potting Mix (see pic for chemical analysis). I believe I may be over-fertilizing. Suggestions?
Thanks.
Eric

Are you measuring runoff pH and PPM? Cannabis and Miracle Grow products don’t get along so well. Miracle Grow submarines your pH and nukes your plant with nutes every time you water. Miracle Grow is also not pH buffered like most cannabis soils such as Black Magic, Roots Organics, or Fox Farm soils are.
I see some wet leaves. The spotting is probably due to light being magnified by water droplets on the leaves and burning them.

I haven’t been measuring anything. I have been misting the leaves with fertilized water - should I stop? Do you think it’s advisable to change soil at this point or do something else to compensate?
Thanks!
Dont must leaves. They will burn from light magnifying through the drops.
