Im not sure what this is. I look upon it and i thought maybe Zinc or Iron def. But im not totally sure.

Whats the problem and how do i heal my baby.
Thanks in advanced.

CD

I don't think its zinc...have a look at the link in the signiture below....there are tons of pics of diff. things. I just put a new link in there...its guerilla something, but it has lots of examples with pics, but it doesn't say how to fix. For that you'll need to click on one of the other links.

Better Pictures.




I flushed it with a perfect pH. Then bought some of this...

I hope it sort it out. Help is needed.

that looks like ph imballance. any nutes till now

Yeah the first set of nutes i have gave it. Looks abit better today, I flushed it before hand aswell.

do you ph the nute/water mix before feeding

yeah had a perfect pH

whats perfect for you?

pH 7 but thats maybe where im going wrong?

stay a bit lower. for use in soil be about 6.3 to 6.7 and the soil ph in that range to. the nutes are more avaliable in that range, and every little point dose make a difference

ahh thats where im going wrong. what so you rekon its a pH embalance?

could be it`s hard to call it from the picture without realy knowing everything about what you have done to them.

yeah, well it seems most yellowing has gone. And new growth is all green. How long should the nutrient feed be from each other?

dont understand. " how long should the nute feed be from each other "
do you mean how often to nute versus watering
