Good job getting started!👊👍 Since your babies (Apple Fritter Autos) are 2 weeks old and in Mother Earth Groundswell soil, you probably don’t need to feed nutrients just yet. That soil has some food in it already. Wait until they’re about 3–4 weeks old or if they start looking pale/light green, then start light feeding.
Start with ¼ strength veg nutrients around week 3–4, make sure your water pH stays around 6.0–6.5, soil for transplant Mother Earth is fine, but when you transplant, make sure the new soil is still good quality and drains well. You can keep using Mother Earth or mix in some perlite or coco to help roots breathe.
Since they’re autos, be gentle, they don’t like too much stress or big transplants. If possible, go straight into their final pots soon.
