Leaves yellowing

I'm 4 weeks in to flowering and all of my 6 plants have yellowing leaves..I've stopped feeding nitrogen about 3 weeks ago and feeding Roots NPK 0-4-5 and molasses. Should I give a light shot of nitrogen?

I'm thinking that the yellowing could be the plant sucking energy from the leaves to the buds. Right now I'd estimate that 10-15% of the leaves are yellow.

It's all good , normal this time of year.

How big are they.....damn sure wont hurt em.

Its all going to the buds to make them big my leaves are almost all yellow but coke can size buds!

Three are 4-5 feet tall the other three are 6 feet+ I'll get some updated pics

Most likely the short ones are indica (fat leaves and a shorter budding time) and the others are sativa (longer leaves and a longer budding time). But in the future you must ween plants slowely off the high nitrogen diet they have been given in the past. Plants still need nitrogen until the flush but MUCH less by flushing time. If they are growing on soil, the N can be shut off weeks before the the flush(N will still be in the soil). Hydro setups will need N just a bit longer. It sounds like your plants are just doing the natural thing and sucking the energy from the leaves and giving your buds a kick in the ass! Good luck with your grow and id love to see pics.Friend request me
