Indoor Grow problem...Any advice

I have been growing quite a while and the last 4 runs i have had the same problem. I grow in soil, under 600w bulb, use co2, nutrients, ppmillion is good, PH is good. The problem is around week 6 of flowering my leaves start dying. it looks as though they are burnt but i use the same amount of nutrients from week 1 of flowering so i dont think its over nutrients, also it happends to leaves that dont get as much light also. It seems to stunt my bud growth. Any suggestions. They get really dry and crisp and turn a yellow

I would assume during that time, you give it less and less nitrogen.

im prety sure its not that you are doing anyting wrong, around 6 weeks of flowering the plant is more concerned with bud production and less with leaf health. the leafs turn yellowish due to lack of nitrogen and bud production uses nitrogen from the plant when they are reaching maturity. you could try using nitrents with more N in them half way through flowering

Do you ever flush? Could be a salt build up over time.

Ive tried flushing and nothing maybe i should try flushing every few weeks. Also I dont think its just the stage in flowering because it stunts my bud growth and keeps them from reaching full potential. The leaves start by turning yellow on the edges and curling then just die. They always look really good till this 6 week stage then its all downhill from there.

In soil Iwould recommend flushing every other watering or every third watering. Also dont water too often. May be root rot. Also take a look under a microscope. If your tricombs are starting to change to cloudy then you should take the nutrient level down as they dont need as much nutrient in the end of a cycle.

Wow that was terrible advice.
Never flush more than once a month and at even that you are flushing out good micorganism.
Many People prefer to keep giving nutes up to harvest being that the last 2 weeks is when the buds gets huge.
You can keep feeding as normal and give a good cure or flush and start/keep giving molases so the plant does not start stressing from Cold Turkey (no nutes).
