Yellowing leaves Please help

[coolone]

THis seems to happen each time. I'm about 3-4 weeks into flowering and the leaves at the bottom begin to turn yellow. I've heard this is normal but I dont want it to creep up the plant. I have another plant that is mostly yellow leaves. Also, the stems seem to have a red/purple strip going through them.

I have been using a low concentration of schultz 10-15-10 since about 2 weeks into veg state. Should I back off, add more?

I'm thinking nitrogen and or phosphorous would help. Does anyone have any thoughts?

stop useing it, it is normal it is going to creep up the plant as long as the buds are not dieing rotting then you are ok.............Do you smoke the leaves?

Stop using nutrients? Really?

Not if I can help it.

if most of the leaves are all yellow by the time you harvest it means the plant has used up most if not all of its nitrogen supply (thats why its taking it out of the leaves) in my experience the finished product tastes alot better as there are less chemicals present in the plant and flushing it will get rid of the remainder. i would start cutting back on nutes gradually and then just use PH'd water for the last 7-10 days before harvest. what strain is it? 3-4 weeks flowering seems a little early to stop giving nutes all together.....

Normal...as plant flowers it pulls nutes from other leaves.. the energy goes to the flowers and not the leaves ... If I find it too rapid I've given a veg nute shot..otherwise just let it be.. Happy harvest..
