The heat did stunt them but not as much as I was expecting, still got about an ounce dry from all of em in 2 gallon pots...
Yeah PH is a bit high, maybe bring it down so the runoff is around 5.9-6.3, but I can't for sure say that is the problem yet.... We'll have to see some new growth after adjusting to be sure that's the issue.... It is possible although not too common that the plants are just weak seeds that have built in deficiencies for one reason or another, however I don't think I've ever heard of these complaints from any JEMs, they're strong growing plants from my experience and others...
