Just keep spreading them around under your screen.. I would pluck some of the light blocking leaves,but not alot. Photosynthesis has to be able to happen. The fan leaves are big part of photosynthesis.Larger leaf,has more stomata surface on the underside.Therefore your plants are getting the co2 that is available to them.

Those small bud sites under the screen... You could get some of those that will never make it to the top of your screen.. Kinda lollipop the stalks below the screen..
