Thanks for the help guys! I misspoke this is the eighth week of flowering. I have one more round of nutrients and then I start the flush. But I'm going to raise the PH and hope the calcium is the answer!
Noticed my girls starting to spot and then all of the sudden the all the leaves are looking like this! Doing dwc, the strain is white widow, PH is 5.8, temperatures are good, and they are in the 10th week of flowering. Any suggestions would be greatly appreciated!
