Is this nute burn, too much light or is it starving?
Help needed: nute burn, light or starving?

Would need way more information for anyone to make a proper diagnosis but a quick look says maybe a phosphorous deficiency. Possibly a ph issue.

Thought you were in hydro. Parameters look good. Are you adding cal/mag?

I
I was told with the H&g Aqua flakes I didn’t need to add cal/mag
Had to look up aqua flakes. Couldn't find a list of nutrients in their product but they do offer a mag. supplement so they know under certain circumstances that it is needed.

I wasn’t aware they made the supplement cause the store I bought from didn’t stock it. I’ll go grab some tomorrow and see if it helps. Ty for that

@CannaQueen89 a cal/mag supplement might help with that brown spot on your leaf in your photos. hard to tell, but it might be the beginning of a mag def (which I've had before as well).
Btw I find that a tsp of espsom salt dissolved in a half gallon of mineral water makes a great foliar spray to apply esp to the undersides of the leaves. you'll be surprised at how they get green again -- because of the magnesium in the epsom salt. (magnesium being a core component of chlorophyl). enjoy your grow! Emeraldo

Is she starving? 40 days into flower.
Ph has been like 6.12-6.40
Been feeding around every 4 days
I’ve been following the feeding chart for general hydroponics flora series.
Adding cal mag in regular waterings to.
Also I’ve never really done any defoliation on these bubble gums. just been letting them grow, so I was thinking maybe it’s old leaves dying but I’m starting to doubt that theory now. Temps have been around 20 to 23 C
Rh has been from 48 to 60. It goes up to 60 when I first water and then slowly settles down as each day passes.

They may not be getting enough pk she starts using from her leaves causes them to turn.colorsIs she starving? 40 days into flower.

@Daniel420 those yellowed fan leaves with crispy tips/ends look to me like a potassium def. Have you tried adding a tsp of seaweed extract to a watering every few weeks? Agree with @Mountainman80 she looks close to the finish, so maybe it's not an issue... Cheers

@Daniel420 my plants had K def during veg this year. The soil I mixed up contained K in granular form and needed more time to break down. Seaweed's potassium content (0-0-4) is immediately available cleared that up. Your K def (if that is what yours have) is pretty late in flowering. Maybe it's not necessary at this stage.
