Help Please first time grow plants are dieing quick

[DANKDAWG]

Thanks it seems I have the PH to 6.4 now so I have began using Nutes again, but i still am noticing dieing leaves is this normal when your plant was locked out or could my plant still be locking up? Should I spray the follage with food instead of the water or something any help is appreciated Thanks

Is new areas of the plant affected or is it the growth that is already affected falling off?

It seems like new areas to me like more leaves that weren't dried up or yellow are turning yellow and drying up

Most of the leaves have been effected, but the top ones are still nice and green the buds are coming in good, any advice?
