[Newbiefarmer]

Nearly 4weeks since I germinated my seeds, first week overwatered, left them to recover, at the begining of second week I watered with(0.25 gram 20-20-20 fertilizer per every liter of distilled water, at then end of second week (0.4 gram per every liter of distilled water water), and in the 3rd week (0.5 gram +3ml cal mg per every liter) , my concern is should I flush next time or keep on feeding them with nutrients since my medium is cocopeat/perlite, Should i flush with distilled or tap water?

distill your tap water and use it.
