Ocean Forest will provide all of the nutrients the plants need for 4 to 6 weeks from your last transplant. Get yourself a PPM meter and begin feeding when runoff PPM dips below 1,000 and then maintain that 1,000 PPM throughout the grow.
The FF Trio is notoriously salty. The nutrient salts will build up in the soil over time requiring a couple of flushes throughout the grow.

@MidwestGuy covered the medium and FF nutrients. Tread lightly in the beginning with the nutrients and only use after the run off numbers are below 900. I would recommend on feed or water days to go to liberal run off but wait until around week 2 of veg after the seedling period for run off. It’s very easy to overwater at this stage…wet to dry cycle and repeat

Thank you I will get the girls ready
Stuck on ppm , if you don’t mind I will tell you my thought on ppm , then please tell me what I’m doing wrong . I add my nutrients to a gallon of water 2- I take my ppm reading and if it’s too low Do I add more nutrients and if I’m to high more water. I never ppm water but this has had me scratching my head for some time . It is TIME for me to get this right . Thank you so very much
Don’t bother trying to get a PPM from what you feed. Just follow the schedule provided with the brand you have selected. Do check runoff PPM and maintain it at ~1,000. It’s not an exact science. You will be at 800 at times and 1,200 at other times. Don’t worry too much about readings that are a little off. It takes time and experience to get it down.
