Underfeeding?

[Lilyungike]

Hello I have a plant in week 4 of flower and I am not sure what wrong with it. Most leaves have turned really bright green/yellowish with veins beeing dark green.
Feeding with biobizz nutes, little less than their feeding schedule shows also PHing my water to 6.5
Growing in Soil
Not sure if some kind of lockout, Mag def or underfeeding or something else
Help is appreciated.

Your grow room could be sort of cold or your plants might need some calmag.

It's natural, the buds steal the nutes from the leaves cause the plant like buds and so do we. If the buds look nice you can let them take the nutrients and let the leaves die. Look at the new growth, if it's healthy the buds are fine. Add some micronutes or whatever and try to stop the natural process if you want. Calcium is immobile and magnesium is mobile so calcium deficiency will show on new growth, if new growth is healthy the buds will be nice.

Thanks for feedback. Will buy some calmag for next grow or add some dolomite lime to soil. Added some epsom salt to this one.

They actually appear to be maturing/aging normally....growing buds seems to siphon most of the energies from the rest of the plant making leaves look starved...but the small leaves at bud sites look fine.
