Should i add nutes?

GH flora trio is a good lineup, in coir you will want an extra CaMg supplement but that is easy enough to find from many retailers. Follow their feeding guidelines and dilute it down to the EC your plants will need, Its good to remember that autoflowers do not like strong feeds like there photoperiod counterparts. GH Trio will always use all three parts just in different ratios throughout out the entire grow. always add micro first then grow then bloom. PH adjust after if needed. can give them calcium and silicon on an alternate feeding schedule as well. https://www.autoflower.net/forums/threads/med-man-method-feeding-chart-ppm-ec.47856/ This link is a good reference point for feeding autos for EC pars to aim for. Best Of Luck!

Start of light, when adding nutes just start with half the recommended dose, I tend to do one watering with nutes, the next just water. Autos are time sensitive so you don't want to run into any issues. Watch the leaves for browing at the tips, if you start getting that then dial back the amounts, maybe use water only a few times to flush.

Please see below website, there is chart, I hope that helps 😊👊👍 https://www.terraaquatica.com/wp-content/uploads/2022/01/TriPart.pdf
