Looking for the pro mix growers out here.. starting a grow using it.. just had a few questions

what’s the ideal ph For promix
ideal form of water (tap etc)
ideal feeding schedules for veg and flower
ideal nutes ..benefit to organics?
should the medium always be wet?
is it appropriate to water and feed to 20% run off?
any tips or tricks are also appreciated

thanks guys

if you use pro mix it's a peat based potting mix that won't provide nutrients persay so you will have to use nutrients. Some people like the Jacks nutrients, cheap, I prefer GH three part, gives me excellent results, massive yields and excellent quality... whatever you choose if you are in pro mix you should run a pH of 6.5 - 6.8.

When you water/feed you should get about 20% runoff out the bottom of the pot to prevent salt buildups. An adult plant will take a feed of somewhere around 1000 - 1200 PPM. If using RO water you will need a calmag product. Calmag gets added first, then micro, grow and bloom if using the flora trio. The chart I put on here is for a 30 gallon mix, so you can divide by 30 to see how many ml/gal. Products are added in that order as well, the Armor Si goes first, then Calimagic...

I hope that answered a few questions for you.
Not sure if quote reply works in another thread but Renfro is your guy when it comes to that stuff.

I use the all purpose promix and mix in 1 part perlite to 3 parts soil.
Had good luck with general hydro trio
This run is the first with an organic mix.... so far so good, liking the water only routine

Ideal ph is around 6.2. I use tap water and my nutrients bring it down into the desired range. Don't let it totally dry out, just water when pots feel light. If you want to go organic you need to add compost/ewc and dry amendments probably with some extra lime. Floranova grow/bloom, maxi grow/bloom, megacrop, and any complete fertilizer will work. Always aim for a decent amount of runoff.

what’s the ideal ph For promix
6.0-6.5
ideal form of water (tap etc)
doesn't matter but you want to have the right amount of nutrients for your water type
ideal feeding schedules for veg and flower
1.4-1.6ec every irrigation. if you see leaf tips burnt then skip nutrients for one watering, then continue with nutrients for the next.
ideal nutes ..benefit to organics?
i wouldn't use organics. hydroponic medium works best with synthetic nutrients.
should the medium always be wet?
wetter than soil yes. it shouldn't always be WET, but it should never be dry. i water plants every other day and they get very light between.
is it appropriate to water and feed to 20% run off?
yes, you must have runoff. elevate the plants out of the runoff too. dont leave them sitting in puddles.
