LOL! Douge did you think I was just dropping by to make digs about your ph? Sorry you didn't realize that I meant it was your problem all along.

Your plants can only uptake nutrients in hydro within a certain ph range. If your ph goes out of that range (as yours did.....alot) your plants cannot take up the nutrients in your water....no matter how much or how many there are in your solution. With an abnormal ph you WILL see nute defs and such things and they WON'T improve until your ph does. Ph is ALL in hydro.
