@James Gandalfini Welcome to AFN. The quality control of the OF may not be what it was 10 years ago. We see it fairly often in the infirmary. The saving grace may be that you have the full line of nutrients and previous experience growing. You did not talk about ventilation but I assume you have some? For autos, start nutrients at 50% strength of the chart around week 3 and work your way up 10% a week until you get a bit of tip burn then back off 10%.
I grow 6 plants in a 4 foot x 6 foot space and it can get tight. You will need more light for the space.
Good to know that about OF. I'll be ventilating pretty simply. Going to build a plywood cover that fits over the door jamb with holes cut for ventilation (one intake, one exhaust) and fans going each way. From there I can line one side with mylar and have it face inward with the closet door slightly ajar. But the closet will still be able to close if needed.
