Can some one help with recommendations for best PPMs in flowering? Master Kush and Blackberry. AN Jungle Juice Micro, Grow and Bloom. DWC. 600w HID. 1st grow was best grow with PPMs at times up to 1500. Reading blogs and studying HHT said keep PPMs at 600. Not so great yields since but there were some heat issues. Heat issues now resolved looking to get back on track. Hoping growers can provide insights on best PPMs for this product. Also running calmag and aqua shield when needed. Thinking grows should be doing better not worse. Thanks in advance RIU.

Not sure about others but strain dependant i run my hydro setup up anywhere from 650- 850 but typically the lower end. I watch my levels and keep it constant. If it rises a lot i add less nutes when refilling and vice-versa. The plants will tell you what they like. Try to keep it at the low end IMO. But im also a newb.

The three part Jungle Juice is just fine. I used a different AN line, but it was discontinued and I'll be doing JJ next. The numbers are very similar.
My PPM rules are simple. No nutes for the first 2.5 to 3 weeks. Then 100 ppm for every week of age, including the natural ppm in my tap water. So at 3 weeks, it's 300 ppm. At 5 weeks, 500 ppm. I go up to 800 ppm at 8 weeks and then hold there for the rest of the grow. In the last two or three weeks I back off to 600 ppm because the plants usually stop taking up nutes at that point anyway and start drawing from the fan leaves. Putting more nutes in the res at that point is pointless and a waste.
I discovered that this schedule produced awesome growth with no problems. It's also about 1/3 the strength recommended on the label, so I save quite a bit of money each grow.
EDIT: Oh, and I also add some cal/mag to the solution. My tap water is 140ppm, so I need to add a little cal/mag to prevent deficiency. And some people have told me that while 800 won't hurt most strains, anything over 600 is a waste. I haven't tested that, so I'm sticking with my 800.
