Always use half strength that your nutes call for. Then work your way up.

im pretty sure this is nute burn cuz its not hot at all.....so anyone HOW DO I CORRECT THIS PROBLEM?...do i flush with ph balanced water or just let them be for a few days since the blocks r pretty wet....im waiting on my ph down i bought, i have some for the next few days so i cant flood my table till i get my order....so plain water or light nutes? i cant seem to find anyplace online that will answer the HOW TO FIX this problem......

Give them pure water next watering, no nutes.

They look fine on nutes, it's heat stress. The room might not be hot, but radiant heat from the lamp is affecting them.

just a few plain ph'd waterings will do the trick

Exactly. That is definitely heat stress IMO. Do you cool your lights? How close are they to the canopy? What are your daytime/nighttime temps?
