I was wondering about that. Almost every product I looked at had more or equal P to K.

A flat canopy is my only goal too. Topping seems easier to me than tying down branches. My plant that I tied the center stem down is now off center in it's netting now and is still growing taller than the rest. The other, that I just topped, has remained symmetrical and the side branches are quickly gaining on the center. I haven't found the need to add netting to it yet. Symmetry is important to me because I like to rotate my plants through out the day in the limited space in my tent.
What I've found with these two plants is that they both seem happiest with the EC no higher than 1.2 or 840 ppm. This morning after topping each bucket with plain water this what I found. One required 6.7ml/125ppm of bloom fert and the other 7.4ml/132ppm to bring them back into the sweet spot. Even though they're from the same cultivar, they both have a little different needs. Not a vast difference for sure, but if I gave them the same everyday one would be out of wack after a week I think. I could probably push a little more but PH and EC remain pretty stable throughout the day so why risk it. I have my leds at 12" and almost full power now and they're loving life!
Thank you for correcting that. For some reason I've got a mental block about K and P.
Yeh (smacks forehead) - the bigger issue is the P gets into the waterways.
Also, P uptake slows/stops at 64° in hydro so I've had to resort to "When the water temp is 64°, it's hard to P."
I run Jacks 3-2-1, same formula from drop to chop. Just for the heck of it, I tried their Bloom product when I flipped my current grow.
The biggest result was to have to add Down to my res many times per day because of the ammoniacal nitrogen. And that's one plant in a res that holds 28 gallons of nutes. Ouch.
Did it do any good? I was reading a blog entry where the author states: "Most commonly used fertilizers in soil tend to have higher P/K values when they target “flowers”, this is because, in soil, phosphorous is not highly available and the supplementation of highly available phosphorous during flower can be very useful to plants. However, flowering plants in hydroponics always have access to significant amounts of soluble P and most actually do not require an increase from this base level when they go into their flowering periods."
The author is degreed chemist, agricultural consultant, and the author of HydroBuddy so I'm thinking that he has pretty good insight into the situation.
I have no reason to suspect that it does decrease yield. Ref my comments about the Frontiers paper. For me, it's a great way to get a manageable canopy and if you water it, feed it, and LTFA (learned that TLA here on RIU just last week!), it will yield a prodigious crop.

well when you top you kill one of the tops and plant is stressed slows its growth for the next few days when you lst same thing happens like in topping just the middle is allsoo alive soo one more top. that could be considered a decrese if in the same time you can get more tops.but if at the end of the day you get same grams then its not
