Using my new HM Digital TDS PH pen question

After reading dozens of pages on TDS, I'm still confused.

For my indoor soil grow, I use distilled water (0 PPM) and I add the recommended 3 tsp of Big Bloom per gallon and get 310 PPM. Quite different from 1190-1330 on their soil feeding schedule. Can someone explain?

Sorry for the confusion. I meant PPM, not PH.

Is that all u used? U need to use a 2 part nutrient solution like a A&B mix... That will bring ur ppm up to at least 1000.

you are reading the chart wrong i use fox farm and in every column from top to bottom you will the grow big tiger bloom all that . then you will notice from left to right it has the weeks well for what ever week your on you go down and look at all the different things will will also need to add

say if your on week five you will need to add 3 of big bloom, 2 of tiger bloom, .25 of open seaseme, and half of micro brew

You are correct sir.

So according to their schedule, I have to use all eight products (at various times) to come to those PPMs? Makes sense but seems over complicated. I'm off to get some 2-8-4Tiger Bloom. That will have to do. 3rd week of flowering with just BB. Better late than never I guess, thanks.

u need to be careful though u will get nut diffency if u only use the main 3 tiger bloom grow big big bloom, u will need the cha ching, beasti blooms, open sesame

Seems to me Fox Farms could incorporate all eight in one bottle for us lazy/cheap growers.

Since mixing nutes together is a no-no, how is mixing a gallon of BB and a gallon of TB going to raise the PPM, aside from checking runoff?

They need to change their schedule appearance.
