5 weeks in flower and losing leaves again

second go at it had not bad results first time out but was hoping to do better this time, got 6 cheese plants 5 weeks into flower under 600 hps cool tube, using bio bizz grow , bloom, bio heaven, and top max, seemed like a lot to me but im still getting leaves drying and browning on the plant. i think it started about 3 and half to 4 weeks in, i give em less than the chart says about 1 to 2 times a week, i hope its part of it but would love em to stay greener and lusher than this so any advice tips or sarcastic comments are welcome, please help

This thread is useless to anyone without pics.

biobizz algamic works great keeping the plants green use it all way through flower

really? using everything else may as well get that too, im thinkin it might be something that cheese plants do, as this is the second lot that the leaves are falling at this stage anyone agree/disagree

info is needed.
PH?
PH of your run off from your soil?
ppm?
soil/hydro?
lights and how close are they?
this is info people need to have to help solve this issue.
to me it looks like a nute burn, probibly cause by a PH
lock up

in light mix soil 600 hps 12to18 inches away, ph is around 6.5 but not done a very accurate reading, do u think maybe flush em ?

ok flush yes it cant hurt anything, raise your lights a bit it might not be needed but id do it.
so PH is 6.5 now what the run off, just incase you dont know what that is capture some
water runing out of the bucket and check the ph and ppm levels of it. also you didnt
say what your ppm are? room temp? I know its alot but there is a salution to your issue
and it lies in these QUESTION
