Hi guys this is my first ever post here I'm from the UK and planning a guerilla grow, exited to join this forum! I've built a small growbox with a cardboard box, tinfoil some led's and a small fan to start them off with to get them to about a month old before I put them at my spot. Anyways I digress, hows this looking for 7 days? It seems to be slightly yellow or lighter green on the new leaves in the middle? I have only given water once the soil has dried out and using biobizz light mix. Any help or comments are appreciated. Cheers!
