Using h202 - which of the general hydro nutes should I not add together with the h202?

[Beezcheeze]

I have the whole line of general hydro nutes and some of their additives also.
Wondering which of the nutes do I not add when using the h202
These are what I have besides the additives for flavor, smell (all general hydroponic)
Grow
Micro
Bloom
Floralicious plus
Rapid start

So, H2O2, hydrogen peroxide, is technically "compatible" with all fertilizers. The key is concentration.

So, your fertilizer is in separate containers because the high concentrations would cause precipitates to form in solution. The same goes for your hydrogren peroxide. It's in it's own container for the same reason.

However, once you dilute everything, it is no longer a problem.

Additionally, you need to know what concentration of hydrogen peroxide. 3% or 35%?

3% H2O2 is the most common first aid antiseptic concentration.

35% can also be found as a food grade product.

For a 30ppm solution of H2O2:
use 1mL/L or 3.8mL/gallon of a 3%
or
use 0.09mL/L or 0.3mL/gallon of a 35%

I do not recommend using more than 40-50ppm of H2O2.

I use the flora trio and h2o2 every time I feed (every third watering) 3 percent. In my 1 gallon water jug I'll fill the just to 9.5/10 of a gallon, mix My ratios of the trio and then fill what's left with h2o2. Kills any bad stuff in the soil and feeds the roots their oxygen. My plants loooooove it.

Heres 2 days later

lol, both your pictures are just about opposite in size. One is as big as my 4K resolution, the other smaller than your avatar.

You're leaves are really purple. While your stuff may turn out okay in the end, purple leaves in the growth stages aren't healthy in the long term. You should only see purple leaves at the end of flower.

That's under the LED...

That's sort of what I thought, but I wasn't quite sure as I saw some green and a lot of purple.

It's 35% h2o2 I believe. Have been putting 60 ml of it into my 27 or so gallon reservoir every 4 days. Also using hygrozyme now to help eat up the seat root matter and the bit of slime stuff that was around the edges of the reservoir.

You're running way to high a concentration of H2O2. 220ppm is way too high. About 3 times too much, and 7 times as much as I recommended.

Dam on the bottle it says 3-4ml per gallon. So I just did 3ml per gallon for 20 gallons to make it less concentrated.

Well, if you added a 3% solution, that's fine. But one thing to consider: Did the bottle of H2O2 you bought come with instructions explicitly directed at hydroponics or plant growth?

Now that I don't think so. But will double check.

 

[MisterBlah]

I honestly doubt it did. So, you can't go off the bottles recommendations for water purification when your application is not purely water purification. Too much H2O2 in hydroponics or in the feed solution in soil will be detrimental.

Here's the 2 left 15 days later. still using the H202. In my second week of flowering.

How many ml per gallon do you think I should be using? Here's mine, the 2 center ones are oh ghost train haze, and the others are 710 cheese.
The og got burnt tips, couldn't handle what I was feeding the cheese. Have cut back now and seems to be recovering. This is my first flood table run and first time really doing it right.. Still in the process of building the flower room and more.

 

[Redishx]

I just feed what my bottles tell me to feed, if the PPM's seem higher than 1.8 I pour a little out and dilute it with water

 

[Beezcheeze]

Yea that's what I was doing, just going off what the bottle said. Think next time I'll start off with like 1/3 as much and work my way up to figure out a safe number.

 

[Beezcheeze]

I've topped these all several times, trying to make for a ton of clones that I can send to flower. Trying to make bushes. Upgrading the bulb to a 600 watt soon

Your plants couldn't handle it, possibly due to high H2O2, but not necessarily. Regardless,

What I said earlier:

For a 30ppm solution of H2O2:
use 1mL/L or 3.8mL/gallon of a 3%
or
use 0.09mL/L or 0.3mL/gallon of a 35%

Alright I'll use that calculation next time I replace the nutes. Will just water it down a bit for now. Thanks!
