Could someone give me accurate information regardi...

Each plant has similar but different genetics. Your plants new growth is showing signs of an iron deficiency which causes lack of vigor. Possible causes are over watering, too high of a ph, temperatures are too cool. You seem to have all of the above. The signs are leaves are drooping down and appear puffy or raised in the areas between the veins. Let them dry out a bit more before watering again. Check the weight of the pot before and after so you can judge better. Try to lower your ph to 6.0-6.3 to aid roots to absorb iron. Also if possible try to increase your temps. If your still having issues try using a foliage spray containing iron chelate twice a week. Be sure to get the underside of the leaves and spray at lights off to prevent leaf burn. Hope this helps.
