Ok Coco&Perlite is good, is it Canna A & B Bloom Nutrients? If so what are the NPK of each bottle?, CalMag is Great for Veg and Almost Half of Flower, Rhizotonic is for the roots, whats its NPK? Probs high in phosphorous so it is usable during bloom. Do you have Great AirFlow in&out, Temps & Humidity? 1 600w in a 3x3x6 can get hot so id assume you have that under control
