strain: Blueberry Cough (currently in week 4 of flower)
Light: 400 watt HPS 12/12
Running a 2x4 flood table.
4inch rockwool in 3 gallon pots filled with grow rocks.
20g reservoir changed every 7 days.
Using Holland Secret Nutriants and basically following there recommended program except for some minor changes.
Reservoir temp is 21c/69f
PH is maintained at 5.6 in flower. 5.9 in veg.
Using RO water

Ok so here is my problem and question.
Second week into flower I started using Carbo Blast and since then I have been battling this, what I would call "Gelling", problem.
At first I was using the powdered Carbo Blast that was very old. I purchased it 6 years ago. A buddy told me it the powdered Nutriants building up so I replaced it with new liquid Carbo Blast.
Now the same thing, the "Gelling", is happening but instead, the color of the Gel is white-ish clear. When I was using the powder Carbo, the gel was dark grey almost black. The only thing in my mix that is a dark black color is Super B+.
This stuff is building up on everything especially my pumps, airStone and PH probe. the PPM are not really effected as far as I can tell.

Dude at the grow store told me to cut out the Carbo Blast since it's doing something funny with one or more of my other nutrients.
My question is, should I cut out the Carbo Blast? I'm not running Co2 so I think this is a bad idea.
I was thinking that I could finish out this round by manually watering the carboBlast once a day. I would redirect the drain to a bucket so it stays clear from the rest of the Nutriants in the reservoir. Then obviously I would have to remember to direct the drain back to the reservoir for the remainder of the flood cycles.
I understand that there will still be residual Carbo in the tray that the rest of my Nutriants will mix with but those trace amounts shouldn't cause my Gelling problem.
So what do you guys think? Does anyone else flood there table from two different reservoirs with different salts?
Is there anything wrong with this. I would obviously want to keep the PH and temp the same in both but the PPM will be way different for obvious reasons. Will this shock the plant?

My plan was to cut out the first flood of the day and manually water the carboBlast for the first flood.

I will post some pictures of everything when I get back to my Garden later this evening.

Any help or suggestion would be greatly appreciated.
I'm looking forward to resolving my problem rather then putting a bandaid over it by doing this manual Carbo watering thing.
