If it isn't insects, I would say it is stressed out due to too many leaves being removed. You do realise by removing healthy leaves you are causing your plant to slow its growth, due to its diminished capacity to produce energy via photosynthesis, right? Those beautiful big healthy fan leaves you removed, produced most of the energy required by your plant to grow properly. They also become "storage deposits" of vital elements needed by your plant during flowering. Leaves should only be removed once they have become yellow. During the time the leaves are are going yellow, your plant will "recycle" those vital elements (carbs, sugars, amino acids etc.) stored in the large fan leaves to use elsewhere, such as for flower growth. If the large fan leaves have been removed, the plant must use energy to "re-manufacture" the lost, previously stored, vital elements, denying this energy to be used for flower growth. Plants can not "channel" energy, energy is used everywhere throughout your plant. Removing healthy leaves reduces your plants capacity to thrive to the best of its ability. Each leaf is like a "solar panel" that produces the energy for your plant - less "solar panels" = less energy produced = less growth. Sorry for the downer, but I DO hope this helps... Organoman.
