I did not work your numbers, so just assuming your math and numbers are correct, it is a tough call.
We are not seeing the # PPM for N as the culprit so much as the RATIO of N in flower.
I personally , between the last 3 runs have seen that in mid flower, 1 3 3 or even 1 4 4 works better, or grows harder, than at 1 2 2 or so. Same in late flower, I saw an increase in yield and density and taste/flavor when I could run 1/4/4 even ran 1/6/6 which really pushed them well…but, remember, I grow @ low ppm’s…talking RATIOS here, NOT PPM. My PPM stays low, it increases only a touch through the run, changing ratio’s rather than PPM to effect plants.
Finding going into late flower, 8/9/10 weeks, the bulk gets added by a 3,4,5 to 1 RATIO favoring K. 1/1/3…1/1/4…1/1/6 blew mine up last run…2 weeks @ 1/1/6 .
So… @ifish …good question . Fish can give his input, which will be the correct input, I can state mine now, lol.
I would like to see more K late in flower, but if that is what your working with, I could go the 1-1-2 I believe. The RATIO is not high enough for me, but in LATE flower , talking 8/9/10 th weeks, I want to favor K. Would rather favor it more, lol, like 1/1/4…1/2/5…but given the two choices I pick 1/1/2 .
I have NOT done it, but with late flower ratio like 1 1 2 I would raise my ppm 200 or 250 ppm over what I run @ 1/2/5, maybe .25 - .5 teaspoon increase.
Do nothing till Fish tells you what would be correct, he will be right, see how close I got…LMAP
Just saw your entering week 7…go 1/3/3 for sure in 7…favor the K next weeks after that…so go 7 more days at 1/3/3…will not hurt a thing . Give fish time to answer anyways…
