Hi there first time grower. I have started two clones given to me, they are just 4 weeks. They are in a grow tent 60cm/140cm with a 250 watt ballast. I have been giving them biobizz grow daily and formulex a couple of times as the leaves were yellowing. I transplanted into larger pots with bat shit soil. A couple of leaves have dropped off is this normal also should I continue feeding them if the soil has nutrients already ? Please you guys any help you can give me would be great !
