Ok bud from what Ive learned id have to say thats probly have to say its a magnesium deficiency that can be quickly corrrected by epsom salt but....... before you do that go to the faqs icon at the top of the page and go into the plant problems section and read about mag deficiencies. Good Luck!!

I agree probably Mag deficiency. They are praying for Magnesium.
