5th week of flower, plants not drinking much

5 th week of flower, plants not drinking much. Doing bubbleponic, techna flora nutes, 3x3x5 grow area, 250 hps.. some of the hairs turning red, mostly near the top of buds, made the mistake of putting sativa and indica in same system, different maturing rates? Although the buds look nice and full, and are firm, scoped the sativas and have half and half clear and cloudy. oops rambling....not drinking as much normal?

Peace

It's ok you put them in the same system. You can harvest at different periods per plant.
IDK bout the drinking, but as long as they are still thriving I wouldn't worry about it.
Mine aren't drinking as much during flowering either.
