when do you stop using it? i used to use the silica armor from Gh but then i got the power Si bloom. it lowers my pH way too much..... do not like using it... even if it is available.... not sure in the end... i quit using anything around week 5 of bloom. new system, new genetics, looks...

using epsom all the time since the switch to jacks both 321 and RO mix, except last 2 weeks using straight part A ... that supplies no Ca and half the normal N, plus tuns of micros ...plenty of sulfur .. :) . we will see.. 4:2:1 K:Ca:Mg is what i've seen...

Doin just fine.. tops look a little foxtaily, light turned down a little and temps are down too. 71f at the top 68 down low, continuing to fatten up.. water and nutrient uptake both reduced. 2.5 weeks to go ish. gettin stinkier. deep green top to bottom, no fade in sight...

so I was reading an article by someone... https://www.maximumyield.com/getting-enough-of-the-right-stuff-calcium-and-magnesium/2/1096 who recomends cutting Ca to 0ppm after week 5 if growing in any "soil like" substrate... I had been growing for some time using 450ppm tap water with high...

if you play with hydro buddy you can add the 321 at 3.4,2.26,1.13 plus (for me) powerSi 2ml/gal, then MKP at 1.27g/gal and MAP at 1.91 g/gal (this mix is for 2.4ec which seems really high to me but thats what Jr Peters recomends so for arguments sake i used that ec here) so if you do that you...

I wrote Jr. Peters about this subject and the rep responded that the 10-30-20 formula was for Tap water with higher levels of Ca and Mg and I think was historically primarily for soil and that the one week recomended period was to avoid possible deficiencies. here's exactly what he said...

thinking the 10-30-20 is for tap water which has Ca usually.... also the K is no higher than 5-12-26. i see no reason you couldn't add Ca to your preferred concentration. not an expert just a hobbyist . i'm debating using the bloom, its only recommended to be applied for one week... maybe go...

i've been learning a lot lately myself. the big thing for me was downloading hydrobuddy from scienceinhydroponics.com . GreenGene has 25min a video on downloading it and getting started... between that and getting microsoft office 365 free version with excel spreadsheets... i can sorta work...

40g Jacks 5-12-26, 20g cal-nit, 7g flower fuel into 10 gal RO diluted to 1.6 ec yeilds 117N 71P 238K 57Mg 86Ca 80S

I was a Pure Blend Pro guy for a while .... always switching between grow and bloom or just running bloom straight through. then i went to canna coco A+B plus rhizotonic cannazym calimagic and silica in tap water (ppm 400 ph9 ish) there is just one formula veg and flower with canna coco...

hows this going?

side note.... i could just swap out my res with another tote bin and use Recharge and just hand water drain to waste for a week or two.... then i could go back to irrigation , probably won't be any issue at all. these microbes reproduce so once im inoculated we should be good to go? and...

same with the Orca and Mammoth P?

I'm getting the impression there is some danger to adding Recharge like this (you know organic hydro and stuff).. whats the worst that could happen? i flow 1 min out of every 5-30 min depending on my mood. the pump is 230gal/hr but probably half that at my head height. reservoir is 10 gal. 4 x...

of note.... the PPMS are probably SO4, based on this information, but would be the same if it was just S myabe i will stop chatting with myself now?

This seems to confirm .. but my GOD why calculate elemental N on the label but not P and K? WHY!!!!!!

but now looky here! it lists total N as 1% but then states 1% Nitrate Nitrogen(not Nitrate but Nitrate Nitrogen) ... Im guessing actual nitrate (NO3) concentration is 4.5% which makes the Nitrate nitrogen 1% and therefore the elemental N as 1% . i think i've got it. :roll: can anyone confirm ?

well maybe i have an answer for myself .. judging from the label data ... it looks like they've done the math for the nitrogen compounds and all other compounds accept the P2O5 and the K2O notice the parentheses; (N) (P2O5) (K2O) (Mg) (S) ... can anyone confirm? i will say that Hydrobuddy...

while Im at it... most nitrogen is nitrate nitrogen (NO3) or Ammonium Nitrate (NH4)most phosphorus is P2O5 and most potassium is K20 but here's what really confuses me... on my Jacks part A of 321 fame the macros are 5-12-26 but to find the elemental ppm contribution you either need to do the...

on the chart at https://dnrservices.mo.gov/ccr/MO6010716.pdf it lists Sulfate (ppm) = 76ppm is the 76 ppm elemental Sulfur or is it actaul sulfate as SO4 and i need to multiply by .33 to get the Sulfur? i lean toward the 76ppm being elemental sulfur and there is approximately 228mg S04 per...
