Ideal EC and pH levels??

Budmizer · Dec 26, 2010

Hi People,

I would like to know what the ideal ec level and pH would be for my approximately 5-6 week old, 2 1/2ft Presidential OG babies should be. Currently in 24hr veg under (4) air-cooled 600w MH lights w/flood and drain system which floods (50)8inch rockwools every four hours for two minutes. 8 inch exhaust with carbon filter and 6 inch intake, mylar on all walls in 8x8x8 room.

EC currently at 1.5 and pH at 6.2

Pics coming soon.

Thanks :peace:

PH is a bit high, indiating your ppm probably is too. 6.2 works, but I like to keep mine at 5.5-5.8. The pant atually maintains that PH beause I have the ppm dialed in for their stage.

Another quick question. The plants are getting pretty tall and I do not want to top them off, I would also like to see more horizontal growth or fullness. How would I go about slowing heigth while increasing width/fullness? Would cutting down to 20/4 light cycle help?

Thanks

So what should my ideal ec level be?

1.5 - 2.0 EC will work for about 99% of the plants out there. Some sativas may feed at slightly lower levels than 1.5 but I can't imagine an experienced grower growing healthy plants at over 2.0. Less is more with feeding so 1.5 is a great place to start.

My personal preference for pH is 5.9.

Ideal EC and pH levels??
