+1 smokey503ski, same here. No issues and great success.
Check for root aphids!!
Check ur runoff as lex0415 mentioned.
Are you using any other products as well? Its possible they're expired, like a bad
cal-mag?!
If ur meter is new or old you may need to recalibrate it. Its possible you're over/under feeding if your meters off. Also consider it with the ph meter if you did'nt already. Get back to basics ya know.....just in case you overlooked something.
My veg cns version is simple, and it works with great success.
week1 veg: cns17, 400-450 @ 6.1
week2 veg: cns17, 500-650 @6.1
week 3 veg: 1ml micro, then 600-800 @6.0
week4 same as above:
week5 same as above with 1/2 tsp epsoms.
Water heavy to rinse thru at least 15-20% of runoff. you wanna clear out any excess salts, if you decide to flush, then do it at 50-60% of strength and you should have no stress. If you change foods mid cycle, flush well (100% of container volume) with the similar strength. Some foods have products that dont play well with others when switching.
NO ADDITIONAL,
CAL-MAG, OR CALCIUM PRODUCT IS NEEDED! Contrary to what people say.
cns17 coco is good but lacks micros, the micro I use is the cheapest I found retail available anywhere nationwide:
advanced nutes iguana micro, roughly 15$ Epsoms come from costco in a blue box and cost 7.50.
Im not gonna start a whole calcium issue discussion, and why its so improperly used with coco medium, but skip it if you are using it, and if its cloudy, toss it. Good wishes.
