I got u. I didn’t know what level u were on. I’ve experienced yellow tips and thought it was a deficiency come to find out my lights were too close. Temps can be perfect but if lights are to close tips will yellow and they can also like sun burn.

Recommendations aren't 100%. All plants have different nutrient requirements. Lots of people start by using half the recommended and go from there.
