Rapid pH change

This morning the pH in my DWC was 5.14 and when I just checked it the reading (5:45 PM) was 6.57 plus getting lots of foam. I have not added any thing in a few days. PPM is near 800.
Any suggestions?

Is the PPM stable, going up, or down? and are you using hi-brix? Some forms of the hi-brix can cause the foam, as well

Well I discovered the culprit in my DWC.

Yesterday I added .5ml Clorox to 12 gallon reservoir, because I felt the slime on the inside of my Reservoir.

This morning I checked and it had gotten no better. So I decided to take the baskets out drain the reservoir and clean everything good.


When I removed the baskets, they were just covered with slime, the res. had chunks of slime floating in it. Then I looked at the roots, dark brown, slimy, and nasty smelling. So I removed them from their baskets and began the long process of washing the roots.

I had to cut them back, which I knew would set me back but it's better then loosing the plants. I washed them in a mild Clorox solution, and then used a medium high pressure spray and my hands to remove the dark brown slim. I got them cleaned well and they look good, well compared to what they were like.

What caused the slime?
After I cleaned every thing and was about to put it all back together I call the maker of my nute package. I told them that I had just used their products once and was wondering if I had done something wrong. Well being a nubie I bought what the salesman at the Hydro store told me would be great, even after I discussed my grow, giving him my method how many plants, age of the plants. Talking to the tech guys at the manufacturer told him the same thing I told the sales guy and he said not to use it in deep water culture, it is an organic and should not be used in DWC as it would slime real bad, foam real bad and stink. I would have thought that he had seen my plants. He was so right on.
So I got fked by the Hydro store guy to the tune of about $60, I am going back there and going to try to get my money back or exchange for the right product that the tech guy suggested. I guess when your new you have stupid written on your face and they will take advantage of you.

I will not be adding any nutes right away, but I did have a product for rooting in the stuff I bought that the tech guy said will work well in hydro so I will be adding that.
I plan to drain, clean and wash my reservoir and check the roots and baskets every couple of days till I begin to see root growth again.

I damn near killed them lovely ladies. They look like shit now but I do have new growth with no damage on the new leaves, so I am hoping I will be ok.

Peace Out

I keep the res at 66 to 70 degrees. It was using the wrong product for the type of grow I am doing. Once I start getting the root system back I am thinking of going to F&D.

Well I guess all that sucks just sucks!
Yesterday I did all the cleaning of the roots, got em looking good again.
Res temp was in the low 70's so before I went to bed I put one of those plastic wrapped freezer bags in there.
Shit, woke up this morning and went to remove the freezer bag from the res and the fking bag had burst open and filled the res with whatever shit they put in it.
I removed the plants yet again and washed every thing again.
This time I put a soaker hose in the bottom of my res and attached the pump I used in my biz for making compost tea. That pump puts out 175 LPM, it really churns the water.
I think they are going to make it, but this has really been a bitch.
If these plants make it, they are tough mothers that is for sure.
And to think I have a degree in Agronomy, and have worked with hydro before. This is such a different plant when growing indoors compared to when I grew outdoors. I will continue to get it all worked out, and I know I will.
I am thinking maybe cutting them all into clones and do a SOG, just thinking don't think I will do it, going to see the mother through.

Peace Out
