Good stuff buddy thanks for you comments that what I wanted to hear! It's my very first grow so I'm bound to be making a mistake here and there But I suppose I'll know a lot more on my second grow, I'm using Jacks Magic Medium, I'm also giving them Canna A+B nutes I haven't give them any bloom nutes, Yea you hit the nail on the head I was a little worried about the flowers but I suppose they will grow do you suggest I give them a blooming nute? Instead off just A+B I go told I could use this all the way through until the end without no bloom nutes I have a few friends that do it with no bloom nutes, Ohh yeah and by the way I woke up this morning and waited until the timer switches them on for 12 and I noticed a few more yellowing crumbly leaves so I think it is nute burn, I'll cut half the dose of what I'm giving them they are on 5ml off each A+B to 2 litres of water, Cheers for your advice buddy.
