Problems

To me it looks like over fert.. I think your ppms went too hi, especially when using Led's.. How many weeks for this strain your running? Do roots feel slick at all or nice and clean white still? PH DOWN = too hi nutrient levels "or" Bacteria in my experience.. Tell us what your water source is (ro, tap) and starting ppms also

my water is tap comes out at 110 ppm just did a total flush just tap pH tested. My roots look good still white very fibrous.

Should I raise my ppm to half strength CS says 700-800 thinking 400ppm.WHY IS pH dropping?

 

[SpiderKid]

How many run's from A-Z with this set up, or is this your first run with it ?

Are you running a pump in your rez 24/7 - mixing it up ..... ?

 

[Growboy]

3 times one time with this type all pumps with system run 24/7

 

[babyhughie586]

have you tried re-calibrating your ph meter??

Do you have well water or city water??

 

[Growboy]

City water and I calibrated last night readings are right

 

[Papa]

did you use cc bud booster in the previous runs?

 

[Growboy]

Yes and I had the same problems pH drop around weeks 5-6

 

[SpiderKid]

I would look into " cc bud booster " being the problem.

One simple test, give them fresh water only for a bit, wash out the top medium, the pumps, lines, ...

If your ph is still dropping with just tap I would follow papas advise and then go with half strength after that.

 

[Growboy]

Ok if a changed my booster from Cs would beastie bloomz work powders from fox farm or what do you think is better?

18-Dec 4.3+ 200 7.1 120 23.5

 

[Growboy]

went back down to 4.3 over night. what to do?

 

[Growboy]

Plants aren't taking in that much water should have more than a half gallon up take per.

 

[Growboy]

Should I run out and get an RO system or is it something else?

thcfarmer.com should get a windows/android app it be cool.

When i add Big Bid, to a fresh Res, my ph drops like crazy, from like a 6.2 to a 4.8 - I beat that ph back up to 6.2, stables after a day or so it seems, i also seem to get a curl on a few leaves , to me it looks like N Tox, i run my ppms at 400, and still get abit of the curled leaf, but 90% of everything else is good, over all growth is great and keeps pushing forward.

 

[Capfan]

Also, my ppms out of city was only 100 or so, but i burn plants at 400 with the undercurrent, i felt like the 100 out of tap was random shit, Get the RO, add only what you want the plants to eat.

 

[Growboy]

Ok well I am thinking I will raise the ppm to about 300 with A&B no booster see how plants do. Will be getting a RO soon. Any recommendations on a booster to replace cc booster?
