Hydro Mothers in pro-mix and GH. Advice needed

So my weak point is mothers. I know the best thing to do is soil, but it just isn't my thing. Most of my growing years have been mono-cropping and taking cuts from veg rooms and not mothers. Now I am just personal and have 7 strains that I need to cut to 4 but am sick of taking care of them, I abuse them so bad.

So my questions are for anybody who keeps mothers in pro-mix with GH 3 part what is your style? Pot size, recipe, etc. And how long do you keep them? 4 to 5 months is all I can manage and then I just make new ones.

Thanks.

I do promix and GH.
I go from solo cup to 1 gal pots. Once they show preflowers, about 35 days from seed, i pick the best female and put her in a 7 gal pot.
I dont usually feed over 700 ppm with the GH flora trio. I cut Micro down to about 40% of recommended for dtw and cut the other two down to about 60% of recommended for dtw.
I use RO water.
If youre going 4 to 5 months you might want to go from 1 gal pot to 5 gal and then to 10 gal.

Next round... just before i cut clones... i will cut the Mirco out completely and use equal parts of the other two bottle to make about 400 ppm for a week or two before taking cuts.

Thank you. Right now I am using 3 gallon so I thought about going up, got new batch of clones going. 700 seems a good target.

pH at 6.5 - 6.8

I always feed around 1000 - 1100 PPM, every watering. 20% runoff.

I use a 50 gallon mix tank with the following:

Armor Si = 100
Calimagic = 150
Micro = 400
Grow = 400
Bloom = 400

I pH to 6.6 usually. 6.5 - 6.8 though always.

Thanks. I have noticed that I tend to get some mg def just using 3 part after a few months. I’ve grown out of the habit of using epsom, wife always steals it for her baths and I’m just too lazy to get it back. What size pot do you use ren?

I am running 10 gallon pots. Watering with 2.5 gallons of feed as required, right now about every 30 - 36 hours. Each plant has it's own thing going on this round since I did 4 per row instead of two and less veg time. When I did 2 per row I was feeding every 16 - 18 hours at this point in flower, way too much work.

10 gallons for your mothers?
