NEED HELP WITH PROMIX

Budz is about the only person on here I tend to agree with. It's dangerous to feed, feed so frequently. Light green growth at the top is normal and will darken over time. It sounds like you've given so much by now that it's surprising they don't have brown tips yet. I'd just let them be for a while. Instead of promix you could use an entire container of ffof and feed very little. Just make sure it's a big pot.

Well my 3 and 5 gallon pots are dry every 2 days. So i would have to feed then water 15 times then feed? Not sure how i would do that
then you feed water water water feed ,or you could feed water water feed, but feed water feed is way to many nutes, no matter what anybody says

How can i lay off the water? The pot is bone dry after 2 days. I water/feed again to 20% runoff then wait till its bone dry 2 days later and repeat
you dont water to drain, you just water a little, just like a house plant.After all, thats all mariyauna is, is a hous plant if groing in a house ,Right?

No, pro-mix company enocalates all the mixes, with a light nutrient mix, do the research. I've actually talked to one of the main peaple from Pro-mix, and that's what they told me.
It's inert.
Now thats its big i water to runoff then not again until pot is dry...i thought it could be mag but did a foilar with epson salts and it disnt green up at all so figured that wasnt the issue
Epsom is fine but the Cal/may should have that covered. If you use Epsom again water it in. Teaspoon per gallon.

Did you water the promix and let it sit before using? I use a similar product and the directions say to water it and let it sit to let pH stabilize.

I've also got a bad bale of peat. I bought four 4 cubic ft bales and one bale was bad. The pH was all over the place. Finally figured it out. Re potted them and it worked.

I bet your problem is under watering. Peat is bad for becoming hydrophobic if it dries too much. Don't let them completly dry out. Water more often and you should be good to go.

No i didn’t water it before using. It doeant say to on the promix hp bag. Just says to use nutes within 6 days of planting and water to 20% runoff. My ph is the same coming out as going in, 6.3-6.4. Ph must be to high or something is blocking something else from being uptaken. Only thing im adding is calmag...im thinking i either need less calcium that its blocking mag and iron or i need more....but cant imagine i need more than 5ml/g with the aqua flakes

Run off pH will have you chasing your tail.

Mix equal parts deionized distilled water and soil then test the pH of the slurry for accurate reading.

The pH of soil swings as it dries for proper nutrient uptake.

I still think more water will help.
 
Sounds like you are using hydro Nutes with promix instead of soil A and B.
You mentioned aqua flakes.
Soil A and B is for soil. Promix isn’t soil. House and garden recommends aqua flakes for promix. Only thing they said was not to add calmag cause A and B has plenty of calcium and adding more causes lockout issues. But when i dropped it i got the cal rust spots on some leaves so i kinda had to add it. Im kinda guessing at this point though. Im kinda playing around with how to water and feed also. I come from coco and adding to many nutes always started with burnt tips but now it seems to have skipped burning and just went to lockout. Ive went from 750ppm to 1000ppm to see if it was underfed and it just got more pale.

Well i flushed with plain ro down to 400ppm so when it dries some i will try not letting one of my veg plants dry all the way and see if that has an improvement.

Soil A and B is for soil. Promix isn’t soil. House and garden recommends aqua flakes for promix.
hello, i use house and garden too. i don't use promix, but a mix that contains perlite/coco/and peat that is pretty similar.

i'm sure you know this, but
i think there is some confusion here. the name "soil a/b" is a misnomer, because they are hydroponic nutrients, and you wouldn't add hydroponic nutrients to a true soil. in the world of growing, the difference between soil and soilless mediums is the presence of fertilizer. soil already contains nutrients. i think the name "soilless a/b" just doesn't make that much sense.

to take directly from H&G website: "Use Aqua Flakes A/B to provide specialized nutrients in recirculating hydroponic systems." so i'm curious, did a rep from the company tell you to use aquaflakes for drain to waste gardening in regular potting mix? or was it just a guy at a hydro store? I was recommended at my hydro store to use soil a/b for regular dtw gardening with any potting mix. Coco A/B is for pure Coco, and aquaflakes is for recirculating hydro.

now thats not to say that it won't work. they are all essentially the same thing. all A/B products from H&G contain all essential macronutrients and micronutrients. so they will all work. but they have different strengths. aqua flakes is about twice as strong as soil a-b in NPK. and has different levels of calcium/magnesium.

having said all that.
your plants look great.
i wouldn't worry about a thing. good luck to you!

Pretty sure everyone in the world growing in peat soilless using house and garden base uses aqua flakes.

you sure can, why not?

just go to the front page of their website tho and it tells you it's designed for recirculating systems.

i just think the naming of soil a/b line doesn't make any sense. why would there be hydroponic nutrients designed to be used in a soil? i also personally don't think it matters which A/B product you use, as i mentioned above.

Try using it. Watch how green your leaves become. Go look at your NPK compared to aqua flakes. Most of us started growing in soil A&B. Its a no brainer. With your current set up you would kill it with aqua flakes. I haven't looked at their website or charts in 10 years.

heard that. if i buy H&G again i will. NPK of Soil A/B is about half of aquaflakes so it does make sense.

i just got hung up on the whole "soil a/b is for soil" thing because it's not really.

Yea the actual rep told me aqua flakes for promix. He also told me to cut calmag as the extra calcium will lock out my plants..here is the email from them. Im just confused cause when i dropped the calmag i got some rust spots on my leaves so kinda had to add some...idk77DBC4C8-82A0-4EF5-B143-8C42F873B1C0.png

The house and garden rep told me those exact words “soil a&b is for soil and promix isnt soil”. So much conflicting info out there its crazy.

Well i cant really agree. My plants at 8ml of a and b and 5 ml of calmag are pale green with purple stems, something is lacking or toxic. Not the dark glossy green in use to coming from coco.

Interesting. After reading that "Soil A/B" makes even less sense to me as a product. Still, I would trust the H&G rep.

maybe try what he says and cut the cal-mag? maybe calcium is locking out magnesium?
