Fhydro, I got those skunk specials doing great, 1st week flower. Thanks for your post. Female Seeds .nl thanks you too.

This is my 3rd grow and I think I finally have the perfect "cocktail" of hydro nutes because my pH is the most stable I've seen. I do have a slow rise like I am supposed to. THis is a good thing because that way I know the plant is using the nutrients. I don't know how much C02 effects the pH though unless it is injected (like Zandor said) into the resevoir.

One thing to think about..... I think pH up bottles and pH down bottles lose their strength and stability after a while. I had a problem with a weird drop in pH (from 5.8 to 4.5 in 12 hours). I have never seen or heard of this. It's always been a fast rise in pH and not a fall. I couldn't figure out what the hell it was so I asked around the message board. Zandor suggested I use new fresh pH up. I threw out the last bit of older stuff I had and tried new. I brought the pH back up to 5.2-5.5 and there it stayed. So....if you have old pH adjusting liquids, I would buy new ones.


what nutes are you using? Tell me exactly what kind of water you use, supplements, everything. I'll see if theres something I can do for you. If you want my recipe, I will gladly tell.
