Getting Worried... like big time

I've heard that the big fan leaves are impoortant for your plants develpoment in both flowering and veg stage.

Im 5 weeks into flowering and almost all of my bigger leaves are turning yellow and falling off most of the big ones get it most but the smaller ones are starting to yellow aswell and this is throughout the canopy even near the top where they are getting tonnes of light


Set up

Flowering: Red spectrum 125 cfl (i vegged with a blue spec version)
Nutes : at the moment shes on 3 mil bloom and 2 mil grow (bio bizz range)
Medium: Biobizz all mix
Temps: 24 celcius on the dot. temps may lower while light is off.

So yea please any help wud be awesome guys
Many thanks!

...looks like your ladies are in need of Nitrogen....however, if your 2-3 weeks from harvest, I wouldn't do anything....most plants will do the same at the end of their flowering.

hey man i was gna leave them another month just incase really want those buds to swell up nicely ill see

Feed them, Looks like Mg deficiency...with the upward curl on the dead leaves. And probably N as well. I would give them a good dose of nutrients, above 1000ppm for sure and be sure you add a grow nutrient so it keeps its leaves a little longer

Looks like it needs a little nitrogen to me. I always give them a bump of nitrogen halfway through flowering.

If I'm not mistaking he's growing in soil. Probably doesn't know what 1000ppm means.
