Not familiar with that specific light.. I recommend this app called Photone if you have to spend.. it’s a quite accurate PAR tool that gives you a direct readout in PPFD. I try to be around 300-500 PPFD in first weeks of veg, 500- 750 after 2-3 weeks, then 800-1000 in flower (1100+ Only increases growth if you are running CO2 as well) I believe 18000 lux is good for your stage. I think that’s around 400-500 umols/s/m2 which is what I was calling PPFD up there 👆 . Definitely crank it to full when flower approaches

From my experience with both, biobizz and aptus are good and would work well in coco. coco is definitely made for fast releasing nutrients(most bottled ones). homemade organics or tabs will probably take more time to dissolve and you'll have no benefits of coco. soil is better with true organics. coco is great with bottled nutes,mostly synthetic I would advise but those two would work good too. No remarkable difference in taste between organics and synthetics I've seen so far. Microbiologic life in the pots decide that. Nutrients that are made for coco like Plagron or Canna Coco AB series bring some explosive growth and good taste.
