Jesus Christ dude, you need to smoke some weed and slow down. You're giving me, and your plants a head ache.

Stop chasing your plants with the pH meter. Set the course and make an adjustment no more than once in a day. TOPS. If you need to make an adjustment more than once a week or so, you need to learn to work your nutes better. But that is an advanced lesson.

For now, fill your controller with fresh water and don't touch the pH! Now add your nutes and your calmag. Now check your pH and tell me if it's not 5.5 to 6.5.

Feed your plants and walk away. Check in a day or so and tell me.
