heard the same thing .....ph 6.6 isnt bad though ...some people say 6.0 others 6.8 ....ph is ok ......I dont know about no 10-12 for seedlings but mine is at 46 and everything is fine so im thinking 123 maybe a little high ...and take what everyone says with a grain of salt ....what might work for one person might bomb for you ...never know ...
BlueDragonSmoke Reviewed by BlueDragonSmoke on . TDS AND PH meters I just got a PH meter and TDS meters. I am using distilled water that comes with a PH of 7.4 and TDS of 002 PPM. I am using Floragrow and floramicro nutrients- the instructions say 1/4 tsp of each for seedlings i added it and stired it. The PH went to 6.6 and TDS went to 123. am i doing this correctly - i saw a video that said the TDS should be 10-12 for seedlings -- does anyone know of a good faq for TDS and PH. Rating: 5
