Hands up I been just adding ml per litre and increasing it as I feel they need it. Laziness and pissed off having gone through two ec pens. Anyway got a bluelab now and plants are looking better for it. Currently got them on 1.1ec during veg with canna a and b. I just wonder what do people get up to during flower. I know plants will be different but roughly. I have used a ec pen before but messed up so many plants not ec related may I add. It's been a while since I've got plant a into flower and used an ec pen.
I'll increase as they need it but just wondering roughly as a guide do people tend to reach during flower.
