If you just planted the clones it's way too early to fertilize them,fertilizing too early & before a plant has the need for added nutrients is the most common & most deadly mistake made by new growers,if your growing in soil & the pot used contains a decent amount of soil there are enough nutrients in the soil for your plant to be healthy atleast one month if not longer,stop all fertilization/feeding right now.
