PH Drama

You should check the EC. It sounds like the nutes are weak.

I'm thinking the same. Low nutes/ low ec.

i dont know because with my current usage i end up with 0,5 l bottle for 1 grow if not even more .... i thought the 0,5 l bottle will last me more then 1 grow since all on videos warn how strong that ph down or up are ... i basically need everyday 35 - 40 ml to get my ph in range

got 18 - 20 liters of water in my rez

sry for liters im a european.

Perhaps your pH down is diluted?
I use 1 drop per liter to bring my pH down from ~7.1 to ~6.2, then another drop per liter to bring it down to ~5.3. I bought mine as a "white label", though, not some name brand.
You need a better source, perhaps? Phosphoric acid...that's all it is.

that is possible i added reallly low nutes to my water since its a seedling got 4 tiny leaves i dont know how mutch my tap water ppm is but from the feeding i readed on labels my low feed should be about 200-300 ppm

i dont know really, but my ph strength is way way less then your's thats for sure i needed 60 drops for 1 liter water to get from 7,7 to 5.5 - 6

Yah, even with the 0.6 difference, I can't see I would need to add that much per liter. Does your pH-down have a name attached?

I'm betting the ec out of the tap is pretty high for you. For me, 10g of ro water (38L) only takes 2ml of ph down to go from 8.0 to 5.5ph. If I have 10 non-ro gallons it takes a hell of a lot more to get to the same ph, and it's about 300ppm prior to running through the ro system. ebay ro filters are around $100 or so, and the one I have works great, has filtered A Lot of water and still reading 0-10ppm after all this time.

hey buddy,
heres one for under 60 bucks

and this one is the one I bought:
its slightly more money, but worth it. It helps having a holding tank, even if it is only 4 gals.

this seems to make sence ...
