have 6 autos running and some of them are showing some yellowing and curling on the lower leaves/tips of leaves are burning and curling/ and starting to get to the top of certain plants. growing in ff light warrior soil mixed with worm castings. hlg 600 watt light set to 380 watts about 38” away from tops of plants. ph is a little high at 7.2 average. just recently top dressed with happy frog all purpose jump starter and doctor esrth power bloom. these babies started flowering at around week 4.5 which Is early to my knowledge. Temperature has been a little high around 80 for a week straight but is now around 75 and 50% humidity. Is this heat burn or a deficiency or a burn ?

What is the pH and PPM of the soil runoff?
The top is definitely light burn and the rest just looks like an overall nutrition deficieny. To me they just look hungry
