Sounds like a good time to introduce a PK booster. Can't say I've heard of Massive, but it looks like a decent combo of PK/carbs which plants should love. Reviews appear positive too. I'd start very slow with any new, untested, nutrient....especially PK boosters.
Only worry would be if it had a very thick consistency and clogging in some hydro systems.
What kind of system are you running Dirk?
Killer garden Dr.Greenthumb!!
well for anyone that cares, the GH blew cutting edge out of the water, same strain, same environment, and the GH plant put out 3 maybe 4 times the weight, Ill put up some pics when I get some time, I dont see how its even possible, Im going to have to run another side by side again just to see. work is picking up and time is scarce these days.
yeah but with only two plants its tough to get accurate results I mean what if one of the plants has better health or what ever. I think a better test would have been like 10 and 10 and do the run like 3 or 4 times and follow the exact same regiments. and then you could see actual results. Ive use cutting edge before and have had way better results with it. my conclusion is basically unanswered.
