botton leaves crisping and dying

I just put my plant into flower about a week ago n my bottom leaves are turning brown an dying. Got them under a 1000 and a 600 air cooled hoods and the room stays about 75 to 85. Got them in 7 gallon pots and some big totes. For dirt its roots organic 727 and regular with happy frog and canna. I also added bat guano, earthworm casting, zho, and azos. Feeding with bionicare, Pure blend and hydro plex. So I got a few leaves up top with a lil lighter green leaves but only bottom and mid bottom leaves are dying. They are slowly turning brown and crispy from the outside of the leave in. Starting to get worry cause the bottom branches aren't showing its in bud, top branches already showing big formation and hairs. Would really appreciate some feed back, this is my third show and I've never had this problem, I was also just thinking about flushing them with ph'd water hoping it might take care of it. This is also my first time using a forum so its confusing as fuck, sorry Gunna have pics up soon just waiting for my light. Thanks for any advice
