G13 Haze first grow flowering problem

hey i'm growing a G13 Haze plant for my first grow in an aerogarden and she's a little over a month into flowering

as you can see in the pictures the leaves towards the top of the plant have been turning a copper/yellow color and drying up...also the top of the big buds seem to have dried out

i have been using the flora series nutrients in distilled water and i'm not sure where my ppm or ph is at

let me know what I should do

no idea but it looks like ur crop is slowly dying on ya ide say get some stuff to check the ph

always start with simple things first, check your ph, check your nutes, then report back, ph should be around 5.8

All yur problems lie with takeing no ph also are the lights that you are useing too close to your tops.
