I took the decision to just FIM the one time this grow and realised I'd luckily made the right choice. I'd also taken steps at the end of last week to change up the nutes. I'm being even more attentive this time round by having a nute mix half way towards the full bloom nutes. I took down the canna A&B but compensated with the CalMag and added quarter strength PK. If there's no sign of N toxicity then I'll keep the Canna at the same level but boost the PK once we're in full flower.
Also notices the first signs of preflower today so I've been really lucky with the timing on all fronts
