End of Flower Week 2 (5 wks from seed): Flowering has taken off this week. Added 1/4 tsp Sweet Candy to the 1/4 tsp of Mega Crop & Cal Mag per gallon. Bottom leaves on all are yellowing and dying off - defoliated. Roots are growing out of holes punched out in bottom of fabric pots, so may be a root, pH (@ 6.4), or nute issue.
Yes week 5 is EC and PH stacking caused buildup in your medium. Since I want to automate watering I'm learning about this and discovering how watering frequency of a somewhat constant content and duration is how you control a stable PH and gradually rising EC in your grow.
The beginning of this recent video shows a good example of steering feeding just keep in mind you have to analyze your own grow medium.

Noticed after vigorous growth in week3 seems there was a stunting between week 3 and 4 possibly from too much dry-back and not enough microbial activity.
