I agree 100%. I try to only have 5% total N4 at most, like 95 ppm of N3 and 5 ppm N4, but only because the product added it. I'm totally scrapping the product next round.

5% N4 (Ammonical) and 5% N3 (Nitrate). Same as me, it just clicked when i saw what people were saying about N4 and it made sense. Literally any problems i had were when it was the N4 added. I don't use any with N2 (Urea).

FWIW some of the pool shocks contain different additives; i always look at the sds safety data sheet. The 3 in 1 is much cleaner than the 4 in 1 as an example. You want the calcium part, not salts. The one i like is 65% and has: HTH Super Sock It Shock Treatment Calcium hypochlorite 65 -...

I meant calculate rather than convert in that case, my bad. To me the elemental values are static for lack of a better term, and the EC is somewhat variable and guesstimated and i agree with what you said. I was trying to relay similar things earlier in thread. There are so many possible...

@Delps8 Everything you said i knew and made sense so i agree with you. The one part i'm not sure of 100% was regarding what you said about RO; i realize plain RO has zero charge but once i add nutrients IMO it shouldn't matter and the readings would be measuring the salts i added that have a...

I agree PJ. I already did the work though ;)

@PJ Diaz It's not talked about much, but the long story short is with substances the elemental ppm is easy to find out with what we're given. The problem is the only way to measure the actual ppm is with lab analyses. So, we use "cheaper" meters to measure the same thing through EC that is the...

From what i remeber last i looked, is that they take into account more variables than i do where they have a somewhat static number that becomes dynamic depending on what your water chemistry, ammounts used of the particular element, and wich compounds were making up the solution. So for 200...

I know what you mean regarding the calculations. I'm by no means an expert but have read enough to at least get thew real ppm right, but as far as the EC there are alot of variables and i can't find a standardized way i'm comfortable with unless you calculate each product yourself and add a...

From what i understand UVC will kill the pathogens but also the roots if in direct line of sight so best to keep it in the epicenter. Also, i think it can cause certain metals to drop out of the solution. I have RO water but in the past used a UVC in my res with plain water before adding nutes...

I have the same problem with meters sometimes not reading any EC, do you happen to use RO water? It's strange how my readings show up sometimes. In my scenario i have 3 meters: 1-Bluelab Guardian, 2-Bluelab Combo meter, 3-HM Digital TDS For a hypothetical example, i'll have 5 ppm RO that...

You are right with your understanding and your meter is fine. I use a Bluelab Guardian myself. All i had meant about the meters is that they rely on EC and then convert to tds\ppm with your formula. The problem is the meters are too "dumb" to differentiate what is actually in your mix...

The first one. If you want 700 ppm you would first subtract your water (20), then in your case Ca (80), and then the remaining 600 is nutes and\or additives. For what it's worth if you're new i assume you are using a meter to get your ppm but should realize ppm on a meter is actually (usually)...

Google Cation, but basically certain medias absorb the P and has a buildup you need to contend with.

Thanks for the input. I 100% agree with the poor planning part that has been my problem and find i learn as i go and add on inbetween grows. To help with the roots clogging the lines i had 1.5 abs threaded bulkheads that i put an abs tee on the INSIDE so that there were 2 points of entry to...

Hi everyone. Long time lurker but i never post because i wanted to make sure i knew enough to give proper advice first. I have a few grows under my belt now and just did 4 strains in a 4 site 1.5 inch abs RDWC DIY undercurrent in a 5x5 tent. I do undercurrent with a chiller but used a single...

I just wanted to say thank you for this thread. I'm starting week 3 of flower in my first ever grow and was starting to plan my next while dealing with current problems as they arise. I find alot of ideas i get sound good on paper theoretically but as i try them i realize how silly or...

I'm in the midst of my first grow (hempy with automatic watering via drip lines and timer) in a 3x3x6.5 tent and ran into the same problem with drainage. The common advice i saw was a flood tray (or alternative) and shop vac. I initially had tubes attached to the hole 2 inches from the bottom...
