I wasn't planning to update as such but I have to say, this is all going great. They've drank 10 litres of that so far and are putting on weight, visibly and no signs of any problems apart from the GG#4...i thought she was hungry because I saw a 2 or three slight deficiencies but it was K toxicity that was locking them out. She fine really, buds are nice. She's on low K now but the rest are more than happy on the Canna schedule with the 0-9-18 PK. Only another couple of days and ill start dealing back the nutrients on them all anyway. I feel happy I'm maxing it though. Even the GG#4 isn't a problem. I just give here less next time but 9 other clones/strains are fine.
