3 days on jack's 5-12-26 and the plants are loving it! Bye bye General Hydroponics forever

weird, huh? wonder if strain plays much of a role in why some can and can't?
Could be strain. I suspect environment plays a role. Most runs were with dual 315cmh over a 4x4 and running Co2.

I've buffered my coco several ways. Lol

I find PH most important for proper uptake of nutes. 5.8 thru 6.2 is my main range.

So I'm growing all of the same strains as the last flower cycle with the exception of blue dream. The only difference is that I'm using jack's 5-12-26 with calcium nitrate and epsom salt instead of GH maxi bloom. The aroma of the flowers is remarkably better and more pungent. The ghost train that I hated last cycle smells more of deep lemon that was not present last cycle. It was a sour burning type of smell that really was not pleasant or lemon like in any way. Just over powering citrus that was terrible. This time lemons. The maui waui smells unlike any maui I've ever grown because I've never grown it in jack's. I've grown if for the last 2 years, but never with jack's. This time it smells like a completely different plant. More like fruit. It smells more like what I would expect a soil plant to smell like. Even the critical mass smells very different. That strain has the least remarkable change, but it's still remarkable. The real test will be the smoke report. I'll do the same 3 day flush like I did last time 2 years ago. Nothing fancy. I'm sold on jack's. Very sold. The smoke report will seal the deal. I have 1 blue dream coming down in about 10 days, so about 2 1/2 weeks out to a real smoke report with jack's 5-12-26.

Okay now I have completed 3 days with Jacks Ro And Epson , Its looking great for the most part they do love it , little bit of transplant shock but 3-4 days in now I can see they are eating now . Need some advice !

Using the ppm x500 /TDS scale
Measured 1/4 strength to the dot on the Jacks RO and Epson

Starting with 280ppm and 5.7ph they are in there 2nd week of veg technically. DTW

Runoff at first was like 10 ppm less than input now on day 4 runoff is hitting 240ppm so that's 40ppm difference to me it means there transplant shock is over..

Question is should I have used more Epson salt you can see from pics below that there are some very green and some not so lush with some calcium deficiencies obviously I know I should use more Epson ... Now should I also Up my ppm so I'm asking let's say I add a 1/4 more Epson to the mix should I also make sure I'm evening it with a 1/4 more Jacks RO as well or I should keep my PPM the same ? And just increase Epson first.

I was thinking doing a foiler spray of Epson now just to help fix the issue happening what is a proper Ratio Grams per Gallon if anyone can give me idea please and thank you..

honestly From what I have been told I shouldn’t need to I forgot to mention I’m running HPA system and this is my first time growing in it and first time with jacks if it where my flood tables in hydroton I would agree..

edit - maybe I’ll take your advice try it out for a day but I just don’t wanna shock them and get set back a week trying to recuperate

That's a fantastic example of how to starve a plant ;) 1.3 - 1.6 EC is needed for healthy plants with jack's 3-2-1. 700-800 ppm on the 500 scale.

ok I’m going to up it but only 2 of them are starved the other 3 are a dark green and healthy . so I’m basing this on my run off and what my run off is telling me is different it’s not like it’s consuming all that much . Will epsom salt increase PPM?

I don't follow the logic. Magnesium sulfate will not address a calcium deficiency.

600ppm won't shock them, it will feed them. just stick to the 321 ratios.

That's what I was referring to. Feeding at 280ppm is not a good idea. The solution to your problem has already been provided by @PJ Diaz . Increase the EC of the RO 1 part to 600ppm and you'll be solid. Happy growing!

Double your ppms.

Jacks RO is a touch low in Ca and Mg, for some. My coco grow included.

I had to use a few ml of Calimagic for defs.

the RO Ca is 7% and Mg 2%. do you know offhand what the 321 #'s are?? i wish the RO had Sulfur like 321.
