Agree with OZZ that it shouldn't be a light intensity problem with the HLGs, things are proper killers and your other results have been excellent. I'm having same heat problem to a lesser degree with the NextLight; i.e. pretty cool in there, which means less than 80f. When temps are low under LED, the plants can't digest the powerful light, don't transpire correctly and affects their uptake of nutrients. Not bad growth, just not optimal and lockouts appear eventually.
Pretty good learning curve with LEDs. Also need extra CalMag. My girls getting it at least once weekly.
