Do I Have a Nutrient Deficiency?

[Aqua Man]

1 gallon per plant every 3 days in 2.5-gallon pots and I was using my normal RO water at 6.75 every other time and When I added nutes allowed it to fluctuate between 5.5 and 6.5. I think allowing too much acidity in the water and not flushing with enough water. I wasn't allowing enough water to flush through the plant, based on how many gallons it just took me to do it.

Imo dont water with pure RO and the watering would make sense as to your issues.

What should I add to the RO water? Maybe do half the dose of nutrients each watering?
