    would love to help

    Hi All !!!! :thumbsup:

    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
