Phosphorus deficiency?

If you need any other help with this hit up your DM's Your inbox is the little green arrow on the bottom right hand corner. Good Luck!

Nah, thats about the right time for some fade, the oldest of the older leaves will fade and die during flower no matter what you do, Just stick to bloom nutes, maybe a PK booster if you want, A lil cal mag but its not vital and just enjoy the color show she is going to put on for you. She wont really need any nitrogen other than whats in the bloom mix, and the PK booster is only for last two weeks anyways if you want a lil extra dry weight. Thats a killer crop you got there too btw. Nice job.

Should follow there feeding schedules and keep the ratios between grow-micro-bloom in your week just adjust the amounts in ml/gal to hit your target. https://generalhydroponics.com/resources/floraseries-feedcharts/ It still uses grow in bloom when following their guides. Good Luck!

I’m using the trio. But the bloom is the one with the potassium and phosphorus so I thought that was really the only relevant one to change.

Which bloom are you using? If it's the flora trio it's not a complete feed without the micro.

Hey your plants look very healthy, the def, I wouldn't worry about too much. They look like old leafs, from past def. It's your new growth that's important and the fsde is very nice and will increase it's just about the right time for that strain. Also, cut out the grow and add cal mag. Mid-late flowering plants l9ve cal. Otherwise mate she's very healthy and a l9vely photo. Congrats.

75-80f daytime and like 67-70f night temps.
