Well we are in week 7 and this girl is just now starting to fill in on her node sites. She is sucking the pH out of the water. I have been gradually lowering the ppm from around 1100... Right now the ppm is around 750 and the next top up I will be putting it down to 550.
She is a 10 weeker so we have probably another 4 weeks to go but I'm around for it.
Good Luck Mate! They are looking great. How long did you leave them germinating for before chucking them into the buckets? Im doing my first DWC grow now
