Hello, I dont know whats going on with my seedlings, they are curling upward and some of the tips are changing colors and literally burning off. Im not sure if its Nute burn, heat stress or high humidity. I have them in a humidity dome the Temp fluctuates between 80-85. The RH is about 79-85%. I have attached a photo of my seedlings. I just transplanted from Rapid Rooters into Fox Farm Little Warrior and 1st feeding was 



water + Fish shit. Any suggestions will be very much appreciated.
thanks in advance
