Having some discoloration on the fan leafs. From a...

hey there Jdizz, that looks like "potting soil" to me, which is mostly peat moss, and actually it's a soiless medium. these store bought mediums are usually treated with nutrients beforehand so you have a certain NPK , and with the slight overwatering the N did slightly burn the tips of the leaves. what's more concerning is the discoloration on the serrated edges of the leafs, that's a cal mag deficiency. so what you need to do is add calmag for the duration of the grow, add NPK starting next week and dont forget an additive like humic acid. Peat moss holds water in more than coco so be careful with your watering schedule moving forward, just dial everything in knowing that you're growing soiless. main thing is dont stress, just stay cool and follow the schedule the plants should recover almost instantly after giving calmag. Hope this helps ! 🚀
