Looks like you switched to flower nutes the same day you went to flower leaving the plant deficient. if so straight water won't help. if that is the case try a mild watering of veg nutes 1 time to try to support it to harvest I start blending nutes for the first week or 2 of flower to keep it...

The foot locker work table is my favorite part and it's about to be converted into a clone chamber. there are a few people on this thread that are going to love the finished room pics. yes it's a swivel, rocking, recliner and there is a tv in the room.
