OVER-watering and/or feeding can also be very detrimental, HOWEVER the more mature, the more forgiving. I'm going to post some pics, once i figure out how (here!) and show you some plants that were dying (overwatered/too small container) and now they are quite vigorus.! OH! I don't "water" i FEED; i.e place measured amount in one gallon pure filtered H2O and then carefully measure allotment; now 3 X day
