Odd discoloration 2 weeks into flower, help

My upper cola leaves started curling and browning during flower. Temp is good 70-76
Water every 3 days fox farm big bloom every other watering. Ph is 5.7. What the hell am I doing wrong? Was the light too close? I just moved it farther away but it was a good 2 feet away…

Feeding only Big Bloom is where you’re going wrong.

Have you heard of the Fox Farms Trio? It consists of Big Bloom, Grow Big, and Tiger Bloom. All 3 products used together (in different amounts according to stage of growth) is a complete nutrition program. A plant will not do well on Big Bloom alone, as you are seeing. Appears to be a phosphorus deficiency at this point but will be a everything deficiency very shortly.
