You really need to know the ppm of your water. See if its hard or if its soft. http://www.amazon.com/HM-Digital-TDS-EZ-Measurement-Resolution/dp/B002C0A7ZY/ref=sr_1_2?ie=UTF8&qid=1370125501&sr=8-2&keywords=ppm+pen
Perfect! I dropped 3 degrees by adding more air to my reservoir too, going back to our convo earlier!
I was thinking my bubble production was weak with 6 watts. 2 three way pumps. Gat any cheap air pumps in mind.
That video series on How to grow DWC will make you a pro in now time! His word is solid! Here is a pic of my DWC.
That's incredible. How much for the pumps. Don't have time for the video right now but will view tonight.
Is your 6 watt a 15 LPH? Anyhow, this is the one I have i veg http://www.amazon.com/Hydrofarm-AAPA15L-6-Watt-15-LPM-Outlets/dp/B002JPEVMC/ref=pd_sim_hi_15 This is the one I have in flower http://www.amazon.com/Hydrofarm-AAPA110L-112-Watt-110-LPM-Commercial/dp/B002JPPFJ0/ref=sr_1_4?s=lawn-garden&ie=UTF8&qid=1370126423&sr=1-4&keywords=air+pump You'll love the videos. The whole series is about 6 hours or so long but hg is awesome!
Just ordered the pump and ppm meter should be here on the 6th. Still haven't nailed down this rust spot thing. Arrrrgh
I set my ph at 5.8 the lowest I've seen it go was 5.6 it was an isolated incident. Still think I should go with a little cal/mag?
Have you not been adding CalMag ? If not, definitely yes, you should go with CalMag or your issue will worsen. If you don't use the CalMag, you could use any ferts of low values that has chelated Ca and add Epsoms salts. If you use Epsoms, buy something like Pennington's, it actually has more sulfur than magnesium.
None at all. I thought that was for RO water. I'm using tap I let sit open in gallon jugs for 2-3 days. Cool, cal mag is getting ordered as well.
