They should have them at your local hydro shop but if they don't then you could try wally world or a pool/aquarium/garden shop?
This is just mho but I wouldn't add nutes until they ask you for it (bottom leaves will yellow from no N). I like to go 4-5 weeks with pure ro water (I use promix hp which is medium hot). Without knowing your ph and ppms its kind of tricky but usually curled burned tips mean over fert. The small foliar spots could be a macro nutrient, but it's hard to tell without the ph. Hang in there though because worse comes to worse, if you do cull those 2, the others will greatly benefit from the extra light and co2
