7 days olds and been fed Ionic Hydro Grow 2ml per litre until slight run off when pot was 50% lighter every 2-3 days and seems to be doing good. Upping nutes to 3.5ml (1/2 strength) per litre next feeding. I'm growing these in natural sun when she's playing out these speed the day in the garden and brought in at the night time, when the weather was a bit rainy they spend there day in a big south facing window. Trying to get them ready for the fabric pots or in ground (undecided yet) hence the biodegradable pots, easy transplant without stalling is the plan. I'm a bit of a newbie and hear you shouldn't feed for the first week or so but I've decided I'll grow exactly as I grow my other veggies which are doing great.
