Beginner grower need advice on plant yellowing

[Numptyswindler]

I recently took up growing and have got two strawberry diesel plants 7 weeks in (3 weeks flower). It wouldve been about 2 weeks ago i noticed yellowing and about 3 days ago it became worse. So i flushed them and began there feeding cycle again.

My grow medium is around 60 peat 40 perlite

For feeding i use 2 part formulas with cali mag, but during flower add *yco swell and supasticky. Feeding every second or third day with a flush every two weeks

The tempreture through the day is around 75 farenheit and 60-65 at night

Not to sure, getting a ph meter today hopefully.
So i shouldnt be concerned about the higher leaves starting to get a bit of purple. Cheers for the response

This is what is worrying me the leaves are getting yellower and yellower daily bud the single blades that surround the bud remain a healthy green

Get a P booster for flower, like Koolbloom, and always test yer ph

Looks like she is sucking up her nutes, kinda normal, but some added P is needed. Look at yer nutes and be sure yer doing later flower schedule for them
