Serious reservoir problem

[greenatik]

I'm having lots of trouble here. I have 30 gallon reservoirs, flood n drain, and I'm getting some serious cloudiness in the water that results in lots of sediment at the bottom of the reservoir the next day.

Here's what i've tried:
15 ppm reverse osmosis 6.0ph
+sensi A - stir real well
+sensi B - stir real well
+sweet - stir real well
+ph up - have to use a ton to get it back to 5.6

i also tried ph-ing the water to 7.5 first, then adding the nutes to bring it to 5.6. the white cloudyness isn't as bad but still there

my plants are experiencing the start calcium and magnesium deficiency

ive read that it could be precipitation from adding ph up after the nutes, so thats why i tried it the other way around. also read that it could be old nutes. is there a way to tell if thats the case without buying new nutes?

Are you flushing fines out of the media?
I also thought cal-mag was a must with RO water, or a nute specifically formulated for RO (with extra cal-mag).

Listen and listen well. I'm being serious and you can thank me later. Just use MAXIBLOOM. That's it. No additives no nothing just MAXIBLOOM.

well i think that this new sensi formula is suppose to be ph/ppm perfect and by correcting the reservoir i'm doing more harm than good

i washed the hydroroks really well before putting them into the system. and the sweet has plenty of mag i never had to supplement cal/mag when using sweet in the mix before

 

[greenatik]

well i can't believe it. my meter was WAYYY off. bought ph indicator drops just to double check and whatya know. the ph came out perfect without any correction after adding nutes.

off to change the rezies

You could add some Drip Clean which will prevent any nutrient salts to bind preventing the need for so many flushes. Only a little is used, so a small bottle will last you a long time.

Are you still getting residue at the bottom of the rez?

add sweet every couple of days instead of all at once.

get an in line filter too and wash it every day or two. and ya cal mag is a must with ro, d

I always use calmag with RO, also I think the ton of PH up makes it cloudy,iv noticed when I add the concentrate to a small cup its cloudy iv never had to add more than 20ml for 20+gallon rez.

What is the medium used in the ebb/flow, hydroton, rock wool or other?

 

[High Country]

Sorry, I just noticed, hydrorocks, what are they?

Well, if you should know if you have old nutes or not. If those nutes have been sitting around for a while or you picked them up on ebay, I would suggest that you replace your nutes and see what happened.

That said, I think you also might want to go back to the other way of growing and then use something besides sweet. Actually, now that I say that, I'm not sure what this means and what I would recommend. I'm guessing that it means something like Bud Candy. If that's the case, use less of that. That might help.

Now, if you have to use a lot of pH up in your grow, that sounds like something more than just the nutes or the way you're growing. It sounds like a grow room issue or maybe even your water.

Check to make sure that your growing methods are clean and then start looking at the nutes and how they're supposed to be used. Advanced Nutrients does have a calculator on its site that should be able to tell you what to use.

Of course, if the nutes are bad, then you can't do anything to help that.

oh shit, i read that wrong,

dude, ph up can go bad after a while, and wont dissolve just leaving a white cloud. try adding fresh ph down as a test in a cup from your rez. if a drop or two of down changes the cloud to regular, just replace your ph up. just had this issue not too long ago, d

well thanks for the replies but i already stated that i fixed my problem - a faulty ph meter. shit was WAY off and had me PH-ing up to 8.0+ for it to read 5.5. I got the colored drops and everything is back on track. they were a little stunted but are snapping out of it. also added calmag into the mix but don't need much of it when using sweet. 4ml of sweet is about 60ppm or so of mag
