The deficiency puzzle, or another look-at-my-leaves thread

[highacutance]

We have Mass Medical's Putang growing under LEDs with Farmer Joe's supersoil in fabric pots. Recently transplanted and stretching just before budding. The new growth on the upper branches has a distinctive yellow edging. I try to stick with water and let the soil provide the nutrients, but this looks like it needs help. Softened well water, naturally in the low 6s PH.

Looks like light bleaching to me

LED's right? Bump up your base feed or add epsom salt magnesium sulfate.

Softened well water? With a salt based softener?

If so the salt is blocking the roots.
