what you're plant might have is a magnesium deficiency,mg helps build the clorophylic atoms that help the plant use nitrogen(which is needed in various amounts in all growth phases)shultz and peters are decent fertilizer's that work best when you follow the instruction's,but they dont contain any mg,feeding every watering is not a good idea either,instead water with magnesium treated water(epsom salt)disolve 1tbs to a gallon of warm water,when it cools,use it to water as usual,they should start coming around in about 10 days or so....bonbon
