New Grower My very first indoor grow....

Looking Good MY! Have you narrowed down your problem? I have found having the pH a little higher -- around 7.0 does actually help better. Sending Lots of Positive Karma your way bro!

I'd agree with TBM on the ph... I prefer a little lower... but I've had steady 6.8's before and done just fine also....

the lower end tends to unloack a little more potential for uptake though...

again:



Am I beating a dead ph meter? :smoke:

Hey Budda What does NFT stand for? I grow SOG in a bubbly tank. My pH fluctuates between 5.8 and 6.5. I once took a plant down to 3.8 to see what would happen to it. The answer was nothing at all it still looked vibrant and healthy but lost all the purple in the stems.

I should of mentioned I usually grow in hydro (NFT) and soilless

Since you are growing soil less, I think the pH is too high and you're getting P and calcium lockout. I'd suggest you try and get the pH down to around 5.8 and start feeding some extra cal/mag. Also, are you leaving the pH probe in the soil for 10 minutes to get an accurate reading?

Dumb question: Is OF considered "soil less"?

OK, Cal/Mag? also yes I left the probe in 10 minutes.

This is what I use: http://www.plantlightinghydroponics...sium-and-calcium-supplement-liter-p-2916.html. Practically must when growing with LEDs.

I'll go to the hippie store Monday! They should have this in stock!
