Very light first feeding with the Plant Prod MJ Boost formula. Its a 15-30-15. 1.0EC, 6.0PH, 1 liter. My water has a starting EC of 0.2. Trying a lower PH this time around too.
Good luck with the grow. I'm on week 10 of my first grow with two sensi-seeds northern lights feminized, and the plants are doing really well.
I hope yours do the business also.
