Grow Mediums Bubble white foam stuff on the surface of the nutrient's rez!!!!

[mecanicu]

Hello!
I just started a DWC system with led's and Think Different seed's .
I've used 1Wx144 Red Blue Orange Led Panel(till now) and 100m3/Min Air Pump for 3 20L Bucket's, now i added one more led panel, this one is a fullspectrum 3Wx100

I purchased a list of nutrient's: 1l Canna Aqua Vega A and B, 1l Canna Aqua Flora A and B, 1l Rhizotonic, 1l Carbo load, 1l Formulex, 1l Canna Calcium Ca 15%, 1l Canna Magnesium Mg 7%, 1l Growth Technology Liquid Silicon, 1l Growth Technology Liquid Oxygen 17.5%, 1l Canna PK13/14.

I germinated 3 seed's and place them in 3 20L bucket's.
Now i'm at day 22.
Yesterday I change rez like so: i mixed 50ml of Rhizotonic, 25ml of Canna Aqua Vega A and 25ml of B, 5ml of Carbo Load (this is new for me, exactly i just started to add this to the rez yesterday), 5ml of Ca, 5ml of Mg, 5ml of Silicon. (Please comment on my nutrient's mix, i forgot to tell, it's my first grow in indoor and dwc)
I used tap water that was left to settle for 2 day's, Ph was 7 and EC 02ms/cm (about EC, i don't know if i read my meter correctly, Hanna Dist 4 Meter reading in ms/cm so maybe i need to convert something here) before i put any nutrient's. After i put all the nutrient's one by one i tested the EC it was 15 ms/cm then i scaled down the ph to 5.8. P.S. ambient temp 26C, don't know water temp but at hand it feel's 20C!

Today (day 22) i notice a drop down of the Ph from 5.8 to 4.2 and a Bubble white foam stuff on the surface of the nutrient's rez and little on the root's. The only explanation i have is that the Carbo Load is doing something wrong (it's the only new nutrient i added) + it like a gel y thing. :no:
If some one that its using Carbo Load can enlighten me about this gel stuff and bubble white foam, I will much appreciate.

I'm posting a shady picture of this foam


Thank you in advance!!!!!

Hey!!!!!
No one here, using Carbo Load?????
Day 26, same problem with ph and bubble foam. Curiously the plant's are perfect and growing like crazy with the added 300W full spectrum led panel. No signs of drop down/yellow life's.

Still waiting for a Answer to my problem!!!

Hi :Sharing One:Had the same problem when adding full carboload to the res with canna nutes, it kind of ferments I think SB said ? .Try 10ml per res max & you should be fine :thumbs:

Whats your res temp?

Def the temp res would help pin point what's going on, the DWC's I've run and had molasses or bud candy in the res with beni's (the rhizo) the bubbling white foam stuff I think may be the beni's brewing and activating which could possibly causing the ph drop along with a warmer res will drop your ph... The better you can control the res temps the more stable your ph will stay... Good luck and if it gets to concerning the beautiful thing with DWC you can just empty and clean the res And start with a new mix haven't used the products you listed yet though I do have the canna nutes to try, so can't be 100% sure pics always help as well... :karma Cloud: things work out.

Hello
Thank you for your answer's. Yesterday the ph started to be much more stable, ph fluctuate from 5.8 to 5.9 so it's all good now. I will try with 10ml of carbo load next rez change.
Regarding my rez temp, i don't have a aquatic thermometer but my ambient thermometer it says 25.5C so my water temp should be around 20-22c.

Any type of carb will cause this especially with Rhizotonic or any other Bennies. I started running advance nutrients bennies and got maaaaad white foam in my res for a couple days then died off.. my plants looked like they were on super steroids so I didnt mind. Just a little of carb goes a long way
