Those never work well. You need a slurry tester.

Mine works fantastic. Expensive though, Kelway Soil Tester I think it's an HB2.
Thank you Hotrodharley.

5.7 water is too low.

5.7-6.2 is what the back of the nutes say. I can’t watch the slurry video yet but I will tonight and see if I have what is needed.

Nice looking. The reviews are mixed.

I have these around for my container Pepper plants. Get's you closer when the issues don't jive.

When discussing the issues with my local shop guy he thinks it is under fed and possibly too hot in the tent. He gave me a sample of cal mag and said it would take a week to recover. We shall see.

That doesn't answer the questions I had. How much of a fert dose do you give and how often? What is the distance from the light to the plants? What kind of light are you using?

After a week of getting more nutes the plants are recovering nicely. I added PK and cal mag to the regular feeding schedule. New growth looks good and the defoliation has subsided quite a bit.
