I would do a maximum dosage H2O2 treatment and then use a maintenance dose till finish. Sounds like either a flaw in system design or some sort of failure...like airstone or pump. Do you live in an area with frequent power outages? Crispy roots?? Sounds grim...

no power outages or anything like that all the airstones and airpumps working no chrispy roots just yellow and the leaves are turning brittle put some aquashield in there like two days ago hoping that will help the odd thing is this happens every time in week five of flower no matter what strain in both systems no matter if its house and garden or gh

In my opinion brittle leaves = mites. Some mites like Cyclamen mites are virtually impossible to see without at least a 50x magnifier. Mites suck the juicy insides out of the leaf for food and leaves them brittle and crispy.
I have only been growing for a year but for root health I use H2O2 with every dirt watering and add it the my hyrdo res every other day. Roots are pure white. I use 29% H2O2 at 1 ml per gallon of water for both dirt watering and in my hydro res.
