Ph Crashing Overnight

i used the Tap for veg this run. worked great, didn't need to add anything else. had some pH issues where it would drop to low 4's. so i couldn't use it if i was gonna be gone but if i was home, no big deal.

wow! nice road trip thru CO. glad you hit the black canyon!!! that used to be a secret spot that not many peeps knew about but the secret is out. me and the wifey camped there and our spot was like 20 yards from the rim. awesome!!

who'd you see at red rocks? what a place to see a show huh??
I saw Twiddle. Black canyon was awesome, but i enjoyed Mesa Verde the best.

one part forums dont exist as a complete 12 mineral form. calcium and phosphorus combine in concentration to form water insoluble calcium phosphate. one parts require cal mag to be complete . that make it a 2 part solution.
I thought that was the purpose of chelation?


Read the part on precipitation.

well for trace minerals yes but not macro nutrients. there is no serious agricultural company would ever tell you that because of chelate you don't need calcium .
1 part formulas were originally made for outside soil .Peter's 20- 20-20 is very well known . they were under thr assumption that the calcium and magnesium would be supplied by the water as calcium and magnesium are the water hardness and make up 70% of dissolved salts in the water. there is not reason to have a one part if it is somehow marketed as a time? saving thing? or whatever. do not know what the focus wound be the only reason that they are kept apart is the calcium and phosphorus.
usually the A part will contain the calcium nitrate, the most common calcium source , and 4hr b will contain the monopotassium phosphate, the most common phosphate source

Well they make Iron chelated for this very reason as it binds with other ions easily. Look at any nutrient label and the iron is going to be chelated.

If they chelate the calcium how will it bind to the phosphorous? I didnt say you didnt need calcium if you chelate.

Obviously its possible to have a one part nutrient because many companies have already done it.

just show pics .this was my last legal grow .I bought the property and setup 36000 watt. each of 4 rows on a floating beam light mover . 9000 watt per 5x45' row .hsrverted roughly 18 lb every 2 weeks.
this was a relatively small one as we were limited to 500 plants. i think I spent about 400000$ cdn .
this is DOCTOR howard m RESH's credibility
he has a phd and ran the plant biology dept at university of British Columbia

calcium phosphate is not a chelated mineral. it is a non water soluble mineral compound. chelated minerals are unusually EDTA or ethalenediethyltetraaceticacid

I dont know how they do it then...Maybe its as simple as lowering the amount of calcium containing salts vs phosphorus containing salts?

Fact is they do it. Any decent fertilizer manufacturer will warn you not to make stock solutions because of this very reason.

Im not doubting that calcium and phosphorus precipitate. Im doubting your comment that no 1 part fertilizers supply all of the plants needs.

post a one part fertilizer in a liquid from that says stand alone.
if calcium nitrate and monopotassium phosphate are combined in concentration they form calcium phosphate.
if they are in a dry form they will NOT form calcium phosphate.,but the moment you dissolve it , it will . it would be very difficult to do so and not concentrating it even briefly. maybe 1 or 2 gram at a time per liter but that would be monotonous and time consuming doing 50 or 100+ liters. even 20 liters would be a bitch compared to adding it straight as a stock A +B formula
