Observation!
Hi,
I am someone who has invested a bunch in sophisticated test equipment so I know how much fun it can be.
What I am going to suggest to you is to ignore your test equipment for a while.
Here is my suggestion to you.
Into 50 milliliters of distilled water, dissolve:
• 4 grams of KNO3
• 1 gram of K2SO4
• O.25 grams KH2PO4
• Add enough distilled water to make 90 milliliters of solution mark it “Macros”
• Dose 30 milliliters on water change day, third day and sixth day
Into 50 milliliters of distilled water mix:
• 1.3 grams of CSM+B
• Add enough distilled water to make 90 milliliters of solution mark it “Trace”
• Dose 30 milliliters the day after water change day, fourth and seventh day
• On water change day, dose 2 grams Barr’s GH Booster.
This for your lighting arrangement, is a bit lean (by my standards it is very lean). Keep the CO2 up make sure everything is clean.
Try this for three weeks or so and see what your plants and critters tell us.
