Got a few ppm questions. Can anyone help?

Don't forget to check you water's ppm before putting any nutrients in your plants. Whatever series you use, just go light and build up as you recognize it's tollerance. Small rather than large amounts are what the plant responds to safely.

Good growing!

I know what ppm is but the equipment i bought is an EC tester......according to the manufacturer of the NFT system i bought, my EC during veg has to be at 1.4mS and at flowering 2.0mS......are these values good?

shouldn't add nutrient ppm to resevoiir that was measured at earlierier time as resevoir level gets lower. Just add Ph corrected water until you change the water in the resevoir , which should be changed every 10 to 14 days.

Here's my recomendation: If the Dyna grow nutes you have give directions in teaspoons or whatever and not by PPM, then just follow those guidelines and top your resevoir when needed with plain water. Keep abreast of your pH level especially when using organic supplements. I think pH 5.8 is a perfect all around level although a light fluctuation between 5.4 and 6.2 is fine too. Dump and renew your resevoir at seven or eight days. Run an airstone or two in your resevoir to keep it fresher. I'm finding my plants don't require added nutrients at every topping of the resevoir. I just use plain (reverse osmosis) water. Don't forget that if you have a small resevoir, like 5 or 10 gallons, you can have a service drop off 5 gallon containers every so often, like Culligan or somebody. Culligan's water jugs are all reverse osmosis treated water. The ppm is like 002 and pH is always the same.

Does that help?

this is day 3 of 12/12 after 30 days veg (including germination). She's my best Grapefruit from Female Seeds available at Dr. Chronics seedbank. Check them out.

storm,
you grew those plants hydro.. in 260 ppm tap water?

WOW.. that is amazing and maybe you got lucky as SHIT!!! Most Hydro and Aero systemd with 200+ ppm water will stunt plant growth beyng 14 days from germination and then slowly kill the plant.

From your picture, it looks like your ppm is to low... it could just be the picture.. but leaves should be GREEN.. capital G.. : ).. other than that your SHIT looks TIGHT!!!!!

congrats on your success with such HARD water.

Last year SNAPPLE had the worlds largest watermelon contest.... HARD water destroyed my chances of winning!! : (

no I do not use tap water. I use reverse osmosis water. The leaves appear a bit light in color from the quality of the picture only. They are much greener than they look in the picture. I follow General Hydroponics phase feeding program with floranova nutes, and all the supplements they recomend including Hygrozyme, and soon Silica Blast. I want to introduce a silica supplement to the mix because it claims to be beneficial to hotter grow enviroments, and silica is abundantly present in soil, and supposedly it will maintain a healthy resevoir.
