When to stop H202?

Been using 35% H202 thruout my grow. Can I use it up to harvest or should I stop during flushing? I would prefer to keep using it to avoid any problems.

I never use H2O2 unless i am having problems with root rot or something of that nature. Rarely ever needed it, but I don't see any problem with lettin em have it til flush week.

I use H2O2 so that I can water my plants with hydroponic fertilzer solution every day getting hydroponic performance in soil (think of it as a once per day ebb and flow). I cut out the H2O2 during the last week that I'm using plain water to flush.

BTW, I use 1000 ppm H2O2 and get outstanding performance at that level.

Fine to use it until chop day. I use 50% grade at 1ml/L every 3-4 days. If I had 35%, I'd use 1.7ml/L.
