Hey people. So I'm 5 weeks into flowering. The buds are coming in nicely but I'm having trouble keeeping the PH balanced in the rockwool. About every 3 hours or so the PH drops significantly and I have to continually increase it all day long.

The top of my plants are starting to look burned? on the tips. I'm sure it could very easily be the PH but it also leads me to a nutrient question. Everywhere I read it says to use somewhere between 30% and 50% strength. However, I'm also reading that your PPM should be somewhere around 1200 for flowering.

I am using the GH 3 part system with (micro, bloom and grow). Following the suggestions on the back I put in 3 parts Bloom, 2 parts micro and 1 part grow. But when I use a 50% mix, the PPM is only at 750.

Any comments on nutrient strength?
Any comments on stabilizing PH?
