i read another user mention that he uses fp through week 3 than switches to grow. Think im going to try route that unless i see a deficiency.

That would be me. The reason I do this is because during the first 3 weeks of 12/12, my plants stretch and very little flowering takes place. If I went to 3-12-6 from day 1 of 12/12, my fan leaves would begin to yellow by the end of the first week and would eventually fall off long before the flowering cycle was finished. 9-3-6 during the stretch goes a long way to keeping the fan leaves green in the event that I screw something up later on in the grow (it's been known to happen!!) If we compare "Grow" to "Bloom" we have 7-9-5 vs 3-12-6. From my experience (and I make zero claims about pushing any envelope of growing), cannabis prefers a 7 on the nitrogen vs 3 during the entire flowering cycle (I use RO water and grow hydroponically.) On the P scale, compare a 9 to a 12; both are higher than the N and the K. On the K side, 5 vs 6...if you or your plants can tell the difference...good on you!!
Please don't take anything I say as gospel; I haven't written any books on growing and I make no claims to being the King, Sultan, Fuhrer, Duke, or Viceroy of cannabis.

i understand your theory. and will give it a shot. thank you. if i see any def's i can always adjust.
Ive heard of people on other forums using fp or grow all the way through. Hate to say it but Big mike from AN Says that cannabis needs more nitrogen and a lot of company's bloom formulas phosphorus levels are to high for canibus. So maybe you are right about what your claiming about 7 being a favorable number I'm on week 3 just using grow 5 ml/ gal and my buds are filling in nicely I'm going to replicate what hb has suggested for now in pro mix, but on the next round I'm Gna try the fp in combo with bloom.maybe I'll do a comparison. Have u tried gro and bloom before or have always done fp and bloom?

I'm looking for a link, but high P induces stretch- a scientific article that looks quite trustworthy says limiting P will help limit stretch... I have read big Mike's "great P myth" but am not sure how much weight I give it...

Okay, the original article has been removed due to the website being down, however it is reprinted here- good stuff: http://www.gpnmag.com/what-really-causes-stretch

It would not surprise me to have good results using FP all the way through, though I have not done so YET!! I have tried several combinations (though certainly not all combinations) and I'm pretty darned close to dialing in what works best for my setup. I strongly urge you to play around with the nutes to see what gives you the best results as strains and setups vary.

Good article, thanks for the link. As I grow inside a tent, limiting the stretch is something I have to be cognizant about.
yea Im not sure either. also with stretch if you keep your temps the same as when the lights are on you will cut it significantly
im in tents as well

In dirt, bloom and grow/foliage pro, are tools and you should use the one your plant needs. I'd say that I use 100% 'grow' half the time I'm feeding during flowering and the other half the time it's a 50/50 combo of grow and bloom. Coral has a great post above, just give them what they need regardless of what the company has named the bottle. Be aware though that hydro is different. While I could probably get away with grow from start to finsh, the NPK ratio of blending grow and bloom at different rates gives me the best yields I've seen from any plant food while keeping the plants green until harvest day.

Well put, sound wisdom... Btw, I have some seedlings started in the promix as I was inspired by your methods/results for such as a new way to keep mothers, and was curious if you found the ph sweet spot to be in the 5.8 or 6.5 range. I'm not sure if this should be considered soil or hydro as far as ph goes?

That pH range is fine. I shoot for mid-to-low 6's in promix personally and I don't have issues.
I also use straight tap with the pro mix I dont think theres a need for RO my taps 63 ppm and 6.5 ph

Yeah, you're fine, I figure the soil is somehow more forgiving, although everyone should be cognizant of seasonal changes to their tapwater content. I have a whole house water softener, which probably leaves sodium in the water so I have to use the r.o. Also, there is alot of chlorine in the tap here, which in itself doesn't cause me any worry as I add my own, but I do worry about the chloramines and other things that happen in the lines. The article HB posted on nitrogen was interesting, I have a feeling DG's choice in nitrogen blend is in an attempt to keep ph steady. Something I got out of the article is because I specifically use chlorine and run a sterile environment, it may kill the bacteria that converts ammoniacal nitrogen into nitrate and ammonia toxicity my be more likely for me with DG(if I understood correctly). So far the Canna I use in the aero rig is all in the nitrate form, so it hasn't been an issue. And because it is made for DTW the steady ph is a moot point. I still look foward to testing DG in here soon though- one variable at a time...
I just installed a chlorine snatcher to get the cloriamine out
do u guys ph when u flush in pro mix? And when do you flush first few amber trichs and then flush 7-14 days out? Was going to use sugar daddy first 3 days and water the rest thoughts? A guy on here HR does that in flood and drain but thought it sounded good to give some sweetners at the end of the plants life

Thought you knew I don't believe in flushing (toilets are another story). I do plan to flush my promix once in a while to address the salt buildup if need be, but that's all. If I remember correctly, HB doesn't do an end flush either.

Exactly! We're not growing toilets here
. I will say this, I don't believe that plants that are fed properly need flushed. I do believe that one should run some plain water through their medium every few weeks in order to wash excessive salts away but in regards to flushing at harvest, I don't think it corrects anything in the plant if it was fed incorrectly. I say this because I've flushed and I've not flushed, assuming the plant was grown correctly, I can't tell the difference between the two. I believe the cure is where smoke becomes smooth and tasty.No I didn't know but it's good to know

No doubt good To know
