Promix HP Amendment Recipe

Hello ROI,

I'm new to mixing up Promix HP to be used with Gaia Green 4-4-4 and 2-8-4. I'm about to transplant a few plants into 1 gallon pots so I'm here looking for any advice, tips, tricks, critiques.

So far my recipe for a 2.8cu bag of Promix HP

15 gal Promix HP
3 gal EWC
2.75 Cups Dolomite Lime
1.5 Cups Insect Frass

I want to cook this for at least a week before I transplant my seedlings into them. One question I had was: what ph water do you recommend I spray down the promix with before it cooks?

Any major things I am missing?

Right now the seedlings are in nursery pots with promix hp right out of the bag with a little bit of ewc and dyno myco. I watered them today with the same regimen as 3 days ago: 6.2 ph water (soft), and 500 ppm all together of protekt, calmag, clonex and recharge.

Here are a few pics so far, seeds were planted 6/30:

I added a couple foam risers for the little guy in the middle

Hitting these mugs with about 400 ppfd of LED in a 2 x 4 veg tent. The plan is to transplant to 5 gal after about 4 weeks in the 1 gal and then flip to flower a week or so after that with half 4-4-4 and half 2-8-4.

Thanks for checking out this thread, I'm determined to grow something worth smoking this time

I grow with straight ProMix HP.

It is ph buffered so no need to ph your water.

That's wrong right out of the gate. Somebody uses untreated pH8 tap water regularly to water their plant they'll be out of range after 4 or 5 waterings and the plants won't like that.

I've used HP for about 15 years and always use RO or distilled water just to avoid pH issues. I'm using organics with it these days but used AN pH Perfect 3-part for years so never had to even think about pH.

High there Tank.

I started experimenting with the same stuff you're planning to do about 3 years ago. Still haven't got it dialed in yet. DWC or hydro nutes in ProMix is so much easier for me but I'm more into growing good meds for myself, family and friends so thought I'd give organics a go after decades of hydro. The first buds I ever grew in '78 were in 5gal pails of farm dirt with dried sheep shit from the FIL's farm so I guess I started in organics.

I've been mixing mine up with 3 types of sterilized manures and EWC. Sheep, steer and mushroom manure with the EWC and maybe just a bit of the 4-4-4 mixed in. Burnt the crap out of my first plants in my early tries. Later I'll add more Gaia Green stuff but just top dress. I use a big serving fork to keep the top couple inches loose and mix in the nutes good just before watering.

I want to have a good healthy micro-herd in the pots so I use DynoMyco in the mix when I blend it up and sprinkle some in the hole when transplanting for the myco part. We get our house water from a dugout on the property so I'll water my pots after a transplant with it unfiltered so I add lots of good bacteria and fungi. I'll add some carbs in the form of pure dextrose or blackstrap molasses and unpasteurized honey to help keep them abundant and working hard for my plants.

I like giving them kelp extracts too. I was using the REMO Velokelp then a guy gave me an almost full gallon jug of it so I'll keep using it. I swear you could grow plants with it alone and might just try a plant with it and see this fall when I get back to sprouting some beans.

I'm not sure about the proportions you're mixing but I bet you can grow a good sized plant in the 1gal container of it before you'll need to add more nutes and by then you'll be moving them to the 5gal. Try sawing the bottom inch off the rootball when you transplant. The remaining roots branch off with thousands of fine feeder roots that spread everywhere in the pots. I've been doing that for years and never had any transplant shock. Usually within a week I'd see roots poking out the drain holes going from a 1 to a 5gal pot. 4 or 5 days seems to be about average.

Looking forward to seeing how this goes for you.

:peace:

Perhaps a little over cautious ?

I wouldn't have recommended it without trying it myself first....

The limestone ph buffer in the ProMix HP has lasted me through flower and I don't reuse it.

Works out to about $5/5 gallon bag. Just not worth it for me....

The GH Maxi series is buffered also.

Keep it simple. Powdered nutrients and water. No additives to ProMix PH are necessary !

Or use IT as an amendment to a custom mix.

Can't help with that as I haven't found the need, yet ? Always curious and try to keep an open mind!

Anyway, Lambs Bread has me babbling bongsmilie

My well water has a ppm of ~500 and the ph is ~7.5

No Cal/Mag, no ph down. Wet/dry cycle, feed at every watering.

600w MH/HPS in a 42" parabolic reflector, an enclosure roughly 5' x 5' x 4' high walls in 10' x 10' x 8' high room.

I just completed a SIX month long grow of three Sativa's and a Hybrid !

Golden Tiger, Wild Thailand, Malawi and an Apple Betty (45/65) from HerbiesSeeds.

To keep the height manageable I cropped about the fifth node and cut off the first nodes.

Then trained sideways until the plants were 20" wide. At this point IIRC the tallest was no more than 14".

Then let them grow up. No issues Except finding out the hard way these girls like a lighter diet than my last grow :o

Works for me....

Rough wet trimmed before hang drying.

YMMV :weed:

Great tips, thank you for taking the time to respond! I've heard of cutting the rootball and I think I'll try it this time when I transplant to 5 gals

Thanks for the helpful post! I learned that I need to supplement with cal/mag because my water is very soft (around 35 ppm of calcium per gal). Great looking plants, chuckeye!

I'll also bet you dont need the cal/Mg product if you use proper amounts of the Gaia Green dry amendments.
If you feel the need to add calcium, why not just try a calcium sulfate product?

Who’s the Malawi from, Ace?
Looks great!!!

I recently pulled some out of jar that had been in the cupboard for a year, and it’s the best high I’ve had in many years and ridiculously potent.

Tuck her away and enjoy this time next year…

Update 8/8/23: Since the original post (7/15/23), I transplanted to 1 gal pots and added 3 tbs of gaia green 4-4-4 to the amended promix (7/21/23). since then, every watering I've been giving growtekt, hydroguard, and roots riot cal mag (soft tap water), finally I've been phing the water from 6-6.5.

So far so good I guess. I started using cal mag every watering to stave off a mg deficency a couple weeks ago. I know I could foliar spray epsom salt but I figured I was low on calcium as well since I'm using highly filtered tap water. Plants have responded well so far.

I topped each plant yesterday and plan on vegging for no more than 3 more weeks or so. Looking forward to transplanting these girls into their final 5 gal pots, taking some clones and then flipping to flower.

A couple questions I had was: Is it better to take clones in veg before transplant into final pot or in the end it doesn't even matter? (Linkin Park)

I forget the other questions but if they come to me I reserved a block of space in case I remember I probably can edit this post.





I didn't LST any of these mugs but the left most one if my favorite. It's naturally bushed out and has long branches. The middle one was the runt of the litter and since the very beginning had this weird light green coloring to the fan leaves that I can't figure out what the problem is. You can't miss it, its only on the middle plant in the pics. And the plant on the right isn't growing much faster than the one in the middle and the structure of the plant is nothing to write home about but I'll do my darndest to get her to the Finnish line.

Since the last post I moved the plants into the 4 x 4 tent and transplanted into 5 gallon pots on 8/16. I added dynomyco and 1 tbs per gallon of 4-4-4 to the pots.

I'm on Day 2 since flipping to 12/12 and added a trellis net. The plants look OK but they seem to be growing slowly compared to other people's grows I've seen. They also have a lot of purple streaking in the stalks/stems and I hear that is usually mg deficiency or ph is off in the root zone. I attached a few pics of the garden, any advice is appreciated!

1st Pic of the lower portion: I think these low leaves are showing signs of stress, that doesn't make me happy.

20230827_163048.jpg

2nd Pic of the top, these plants aren't very tall yet but the trellis net is keeping the branches down

20230827_163039.jpg

3rd pic is the overhead shot, one good thing so far is I think the green is a nice healthy color- not too dark or too light

20230827_163032.jpg

The final pic is a close up of the purple streaking. I'm growing Chem 91 x Chem D so I doubt the coloring is related to genetics. Hopefully I can still get some good smoke out of it anyway

Update: 8/31, 6 days since flip to 12/12

I watered last night with some Neptune's Harvest Fish & Seaweed Fertilizer 2-3-1 (1tbs per gallon) I watered approx 4gal of water into 3 5gal pots. Next time when I water I will use at least 5 gallons of water between the 3 pots in order to get some run off. Anyway, the plants got huge since last night. Since uploading these pics, I'm noticing maybe they need more nitrogen, the leaves don't look as dark green as a few days ago.... What do you think? Here are some pictures:

Update: 9/10 (16 days since flip)

A lot has changed since the last update. Found out the mug in the back left with gonads the size of Gibraltar! It must've been 9/1 when I noticed the balls goin out the wazoo I said to myself, "Holy smokes I need to cull this mug before he jizzes on everything". Anyway, got rid of it and now there are 2 plants in 5 gal pots in a 4' x 4' x 8'

I have good news in regards to the red/purple streakings in the stalks. Since the last post I have been watering with roots riot calmag (0-0-0) and recharge,@ ph 6.3. Most recent runoff ppms were 1450 and 6.5 ph

I'm on a schedule where I water ever 3 days. The next time I water will be 30 days since last top dressing if Gaia Green. My plan is to use the bloom formula only and supplement N with earthworm castings and neptunes harvest fish & seaweed in a pinch

Its officially day 16 since flip, the girls are growing and they have what they need. This is my first time running anything out of the chem family. Thanks to Lucky Dog, Top Dawg, Humboldt CSI and the rest.

A few tent pics:

Update 9/13

It is now 19 days since flip to 12/12. When I watered yesterday I top dressed with 1 tablespoon per gal of gaia green power bloom 2-8-4 and about 2 cups of earthworm castings per 5 gal pot. I amended my water with roots riot calmag and real grower's recharge. One thing to note: when I watered it took way longer because the EWC must have mucked up the works. Next time I will only add about 1 cup of EWC to prevent the compacting of soil. Not to worry too much, gravity took it's course and everything seems to be OK. From the pictures, I noticed what may be a nitrogen deficiency on the rise. I took a few pics before the lights came on today to maybe give a better idea on what color the leaves look like. Anyway, my plan was to do a final defoliation type deal on Friday before I water. This final transition to bloom phase has always given me the business. All tips, advice, critiques, suggestions encouraged. Thanks for stopping by. Now, on to the pictures:
