Hi DemonicAngel. Such a contradiction of terms. NICE!

I spent the morning doing Nitrogen, Phosphorus, Potassium, and pH tests. I have two different test kits from Luster Leaf. There was differing results. One reported high NPK and the other was reporting low NPK. I have four different ways of measuring pH and they all say LOW for the Soil, 5.5 to 6.0.

So, if I understand you correctly, (thank you very much for sharing your experience), there is a nutrient deficiency in my soil. I use Fox Farm nutrients. What do you use? I'm using Grow Big and Big Bloom at the moment, but as flowers are showing I will be adding FF Tiger Bloom with the Phosphorus and Trace Elements. Do you think this will be ok for now?

Checked your ebb/flow setup thread. Hope all is well there...

I use advanced nutrients. You should be fine with your plans and my ebb and flow is doing ok. Not the greatest but my first try at it lol. Making the transition from soil to hydro is a bit shall we say different lol

A dose of Nutrients seems to have worked. Thank you DemonicAngel. There is no sign of lasting discoloration at the tips of older growth and newer growth is underway problem free.

I'm glad to hear that just keep an eye on it and you'll do great with the CKS Northern Lights auto
