Feed your widows sat and mon (my schedule as well) and just water inbetween, wed since that is part of your current schedule. You should notice a difference fairly quick.
OH by the way, Is tiger bloom a full NPK flowering feed tea? or just a bloom booster? You should be able to tell this by reading the ingrediants on the bottle.
If it is just a booster it may not have all the required npk's that your flowering girls need. During flowering they still need nitro, potasium, and phosphorus at different levels than veg time. Boosters are added in addition to the basic food and can be used everytime you water. If tiger bloom is just a booster more than likely it has no nitrogen which would cause your leaves to yellow from a nitro defiency.
If it is a full feeding system then feed em 2 times a week see if this helps. Kathy
