Hi All !!!!

stoned88911 would love to help you out on this.

A photo or a description of spot location on the leaves would help a lot.

Miracle Grow could be the problem, if applied to heavily.
Also I personally would not use Miracle Grow soil of any type.

I suggest loosing the Miracle Grow soil, for sure, and re-pot in a good quality
soil without fertilisers added in it. Personally I use Fox Farm Ocean Forest with good results.

If using Miracle Grow fertiliser mix to 1/4 strength, also it is missing the micro and Macro Nutes your plants need. Cal-Mag a definite plus.

You can grow with Miracle Grow, but its much easier with a better quality fert.
Good Luck

The spots are appearing on the lower leaves, just randomly all over the leaf

I just baught some fafard No nutrients potting soil, was gona use it along with perlite when i xfer plants into bigger pots

Potting Soil : : Fafard does this look like good soil?

scrath that, i just got 5 bags of foxfarm ocean forest.
Do i add perlite or anything to it?
