HELP…WHICH DWC NUTRIENTS SHOULD I USE?

[NewGrower24]

So just purchased a DWC system, growing auto flowers this run, and could use a little help with choosing nutrients. Have very little experience in hydroponics and not sure what would be a good choice. I have a fox farm trio pack from previous, but I know from the past that one of the 3 fox farm nutrients does not fully mix in water. It’s always in the bottom of container no matter how much u mix it, and I’m assuming that would cause a mess in my DWC system. I really need to purchase the nutrients asap so, if anyone has some help or ideas I would really appreciate it.

Thanks

The various brands of hydro nutes all work. As you pointed out with the FF stuff, you want to avoid anything organic/insoluble. On the lower end, cost-wise, you have dry lines like Jack's or Masterblend. If you like liquid synthetics, the GH Trio has been around for decades. On the pricier side, people seem to like Athena and Advanced Nutrients. Those are just a few options. There are dozens, if not hundreds. For the most part, they're all made from the same commodity agricultural chemicals. I've had good luck with dry nutes, but they're a little more work to mix.

Thank you for your response. So if I was to go with Jacks dry products, which products should I get? Is there a starter kit or a certain combo I need?

The classic Jack's 321 recipe is 5-12-26, calcium nitrate, and epsom salt. Jack's sells from their website, and at retailers including Amazon. If you want to start smaller, you might check eBay.

Here's the video that got me started with Jack's.

Do you know how your water quality is ?

The PPM levels in my water is 800, which terrible and IMO unusable.
I wouldn't use water that the PPM's are above 300 PPM's.

I use advanced nutrients at about 3/4ml per L

I used to use hydro gaurd as a beni
But I never had the results I wanted

I just use sensizym now at 2ml per L
Roots are whiter than they’ve ever been

When going hydro u need to decide are you going sterile res or beni bacteria

If sterile use h202 at about 1ml/3ml daily preferably 3% peroxide,
This will kill all the bad stuff in the res,

If using benis don’t go near h202 as this will kill your good stuff nd only damage the roots,

Water quality is important like stated above,

My water comes out the tap 80ppm x7scale

If harder than 300 I’d recommend a water filter

The first 2 weeks in Dwc I wouldn’t change the res nd let the root build their protective layer, changing in the first 2 weeks can strip this layer from the roots nd invite problems

I’d personally recommend general hydroponics Lucas formula for your fist couple times should get great results

All the best happy growing

masterblend or jacks or some other dry nute

I like general hydroponics trio and I only use it at 50% I found autoflowering plants in dwc need very little food

I concur with above. Not all nute labels are the same though. Some are primarily exotic single-source organic without even listing it like H16, whereas most solid salt lines are literally just whitelabel lines from Jack or Yara anyway....

Jacks or Yara if you are expert level and willing to go through with water testing prior. If you do it this way, you'll be near $0.02-$0.10 per gallon. Solid salts have a heck of a solubility issue compared to liquids though, so if you're having trouble getting liquids to be homogenous in your water I'm curious about water quality.

I honestly just switched last month from Heavy 16 to Kosher. Heavy 16 never let me down but with tariffs in the USA I'm sure they're going to get demolished on prices soon. They were already expensive. The dude at Kosher Salts absolutely hooked me up. It is as simple as it gets. About $0.20-$0.30 per gallon with him. I have had no solubility issues but I filter my tap heavily.

Always go half strength, with any vendor. They quite frankly don't know what they're talking about. Most modern research programs are looking at PPM for macro and micro for cannabis and proving we are way overdoing it... Change that water often, and keep it bubbling and you'll be fine
