Royal Gorilla and Green Gelato

I took a top off each as a tester on day 70, which is the long end of Royal Queen Seeds estimate. Still drying, but I will update when done. Does the foxtailing and bud development look 100% heat related, or could it be too much nitrogen in there too? I'm really impressed by these strains, they've stayed very healthy the whole time and despite the heat issues, smell better than the autos I've grown, possible exception of Barney's NYC Diesel, that was very nice indeed. I have popped a couple more of each so will be starting a new diary soon when these finish.
