I decided to renew nutrients and water completely, even though very close to the flowering stage, and I'll have to do that again. Some leaves were showing signs of nutrient deficiency.
Started to trim and firm 3 of the plants. The BBP2 is still the runt, and I'm not holding out much hope for it in the long run. Mix 1 is starting to look more normal also.
@OSGoldskoolgrower, Thank you. I see you have a nice grow going, and it's funny you mention that, as I was thinking the Mix One in the back might be a Zkittlez Auto.
@BudBoutique, Thank you. Now they are in flower, I've realised this is one of my best grows ever. Shame about the little Purple Punch Auto runt; if that had grown like the rest, there would be zero space left in the tent. Another week, and I'll add some CANNA PK 13/14. Hopefully, if the timing is right, there will be some nice big buds at the end.
@Growingwithjase, my first grow using DWC, even with all my mistakes, gave me a bigger crop than I've ever had with soil. So glad I moved to this method.
