what is your ph and ppm? are you using a bloom formula for bloom?

 

[GManHollywood]

ph is 5.5-6.5
ppm 800-1100
Flora Micro/Grow/Bloom

Looks like nute burn, might be heat/light burn. Have you flushed at all during your grow? How close are your lights and what are your temps?

Keep your ph nowhere higher than 6.0 and no lower than 5.8. The plants probably would have withstood the nutrient levels if the PH was exact.
