Ph of my tap water is 8+, after adding nutes it brings it down to 6-7ish... They were repotted two days ago, from 1gal container, roots were everywhere... Brown spots started apearing the day after, mostly on older/middle leaves... I have used regular tap water with 8+ph when watering after repotting,didnt want to over nute, I think I might have messed up with the ph of the soil... from what im seeing it might be a cal/mag deficiency due to lockout...but not positive.. should I flush them with ph ajusted water? Any other tips? Thanks!
I wouldn't flush, what will that do? Getting some cal/mag seems the best thing to me. Compare your leaves to the pics on this site and see what you think http://www.growweedeasy.com/marijuana-symptoms-pictures Having problems of my own with phosphorus...
Thanks for the reply! looks like calcium to me from that link you sent me... any other input is appreciated
If you want your plant to improve, sometimes you have no choice but to flush if ph is skewed. I notice you gave attention to ph in your water and nutes, but you mention nothing of ph run-off. If you'll measure ph run-off and adjust soil ph from there your girl will improve. Damage is permanent, Ca spots will remain.
