Also feeding FF trio for the 1st time as well. Started with Tiger bloom right before flowering, but didn't use anything else until then b/c of funds. Next clone batch will have all 3 from the start, already noticing ALOT faster veg growth now. I just used the FF online schedule. I started at 1/2 strength on all, then gradually worked up to regular doses. All seems well and pH is still stable. I did boost a few feedings lately, seems ok. I fill 1 gallon jugs with a premix and regular water every other feeding. 4-6 weeks left im hoping. Good luck!!!
