My plant is 39 days into flowering and some fan leaves have some sporadic yellowing/browning and it seems to be working it's way to the top from bottom. however not all leaves on the bottom seem to be effected. i purchased one time ph/nutrient testing tubes. apparently my soil ph level was 8.0, which was ridiculous in my opinion cause the plant was fine until a few days later. Any opinions?

Thanks for your time...
