Yellowing & browning but unsure why

Hi there, new here, first grow.

Soil Grow (Vigoro Organic Potting Mix & Perlite) @ about 2 months in...
Blueberry fem Indica
Only growing three plants in a 3x3 space.
Lighting: Apollo Horticulture GL80LED Full Spectrum 240W LED Grow Light (supplemented with big full-spectrum compact fluorescent flood light & sunshine from a window.)
Temp is kept around 70-75F and humidity around 50%.
I water every couple of days, when the top inch or so is dry.

At around a month I added some 5:blushsmile:1 fertilizer and for some yellowing & browning so I thought nute burn and went back to just water. But now I'm still getting yellowing & browning on the older leaves, and some paleness on the upper leaves. Now I'm super unclear what the problem is. Nitrogen deficiency? Too little light? Too much light?
