Let me do some homework on it. Thank you
Have you tried Athena PK?
Potassium suflate, and if you want to keep a specific K:Ca, add calcium suflate. Don’t mix concenrated K2SO4 and CaSO4.

Honestly, it depends on the conditions in your grow. Are you using CO2? Do you have an optimized environment as far as your Temp, RH, and VPD is concerned? What media are you growing in? How much PFD are they getting on the reg? Slamming the gas pedal down on your plants could have some undesirable effects if conditions aren’t right for it and result in nutrient lockout and salt buildup in the root zone. And if the plants aren’t in a good position to make use of the extra fertilizer, ie boosted by CO2 and bathed in adequate light, the risk of that happening is increased.
Coco in particular I’ve noticed has a strong affinity for holding onto salts and skyrocketing the EC in your root zone, so if other things are out of whack as well it might actually be better not to juice them.
