I haven’t used these products, but here’s my thoughts. Your soil should still contain some nutes, although they my have dwindled somewhat, so you’ll want to start light with the bottle feeds. I’d start at their week four schedule, but only 1/4 strength, and watch your plants to see how they respond. If all goes well slowly ramp up the dosage each feeding. Some photos of your plants size and pot size would be helpful. Goodluck!
