The only thing I can say with certainty is that I am really liking the results of running the 7-9-5 for the first 4 weeks of flower. I have been running a 30/70 mix of well water/ro that gets my ec to less than .4. I am going to go 100% ro starting next week.
This last rez. change I mixed in 25% 7-9-5 into my second stage rez in flower and made the balance up with 3-12-6.Next rez. change I will prob. go 50/50 bloom/grow for rez 2.
I have also been running 2ml/gallon magpro and 2ml/gallon protekt in flower and veg. Which I am suspecting is too much in relation to the foliage pro, and to a lesser extent the grow.
I am showing what seems to be a zinc def. in veg now. I am not 100% on this though as the symptoms don't EXACTLY match the pics I have found online. It seems that no matter where you look deff. symptoms up they all use the same stock photos.
This last rez. change I cut out the magpro entirely and cut my protekt in half in veg. I made the balance up with the 9-3-6. This was yesterday tho so I don't know if this was good or bad yet.
I should add that I am just coming out of a major fungus gnat infestation and I caught some root aphids before they got out of control.
I got rid of the aphids with an imid drench in veg. about three weeks ago and have been drenching with gnatrol 2x a week since for the gnats so some root damage is present on the older plants that I am sure is causing some of the symptoms I am seeing.
Some of the recently transplanted clones were also starting to show def. symptoms prior to my rez change yesterday though so I am wondering if using too much of the magpro was locking out zinc. As the magpro is super high in p. I am just guessing here tho.
The gnats are damn near gone and I haven't seen an aphid in two weeks. I have some of the best roots I have seen busting out of the 10" netpots my moms are in and overall things are looking better than a month ago but I am still experimenting some in veg with the fol. pro.
If the def. symptoms don't start clearing up in veg. I'm gonna go back to the 7-9-5 I think next time.
Anyways, sorry for the absurdly long post but that's my story.
