Wedding Gelato Outdoor Northeast USA

3 of the 5 plants are close to harvest. Calyxes are plumping up. My "ripest" plant has had browning of the oldest calyx clusters, which at first I thought could be rot but it's not - simply, all buds aren't ripening at the same time. I have been tapering the feed except for my one Critical plant which is several weeks behind the other Wedding Gelatos. Interestingly, Critical is supposed to have a quicker flowering time but in my situation it is definitely not. Weather continues to be seasonable warm, still seeing 80s in the day, mostly upper 60s at night. Looking forward to Croptober.
