I have 2 strawberry kush strains I purchased through ILGM and previously had problems with my grow medium. I changed my soil and nursed them back to a healthy state. I gave them their first feeding with dyn-gro foliage 4-5 days ago and yesterday watered them with tap water I let sit in a jug for a couple of days. I just ordered a PH scale so I’m not sure what PH the water is or the soil. I started to notice curling in the leaves of one of my plants and couldn’t figure out if it was nitrogen toxicity from that first feeding or if it was heat stress. My temp in my grow room stays around 73 degrees during the day and I leave a fan on all night and it stays around 79 degrees all night with the humidity level between 30-37%. I was wanting to know if there was a problem with my little lady and what should be done to fix the problem.
