It looks as though at one time it was very happy, but in the last 7/10 days you have done something diffrent, id say you have put the light down and its doing its very best to get the fuck out the way, put the light as close to your face as you have it to your plant, id say thats your prob, if you dont have a fan try and get one, dont blast the plant/plants they just like a breaze, not a hurricane, 2 small fans are better than one big one, then the other fan can be aimed at your light helping to keep it cool etc, only feed your plant when the pot is very light but the sides are not coming away from the pot, its also best to put your pot in a bucket that has the nuits etc in it about 5inch deep leave it for about 5 mins and the plant will take up just what it needs, just keep the bucket etc for next time, but good luck.
