SOIL Spots

[Zayne1958]

Doing a six plant indica grow in Fox Farm soil. Plants are looking good except for one Critical plant which is the fastest growing plant of the six and has developed some spots on a couple of the leafs. Any suggestions will be appreciated.

Check your PH. make sure it is between 6 and 7.

Looks like the beginnings of Mag deficiency. Something is off in your nutrient ratios. What are you feeding it?
