You'll definitely want to bring your pH to at least 6.3 at minimum IMO and at 6.8 MAX...I shoot for 6.5 as that's in b/w :jointsmile:

Also, the soil could be a possibility but doubtful, being that your just now seeing these symptoms. Usually if the soil is too harsh you would have seen those problems in the seedling stage.

Either way, fill out the form for a definitive answer!
