I can't seem to stop it. I have been watching it for a few weeks, because this happened in the first plant I flowered and she ended up killing most of her older big fan leaves in early flowering and was fine in the end. But I assumed it was because I was starting her out on very weak nutes. I halfed the recommended amount and then quartered that... I thought she was just hungry. So this time I did 2 things differently to try to combat that problem.. I flushed her for about a week before entering flowering, to get rid of any salt build up to make nutes more available. And I started her out at 2/3 of the recommended dosage of bloom nutes to start so that she would have what she needs. I thought that I was over watering her, so I backed off on watering. Whatever I did is not working. This necrosis is working its way into fan leaf after fan leaf.. I don't have pics because my girl took her cam back. The grow shop people told me that flushing in transition is a myth, and should not be done, rather make a solution of bloom and grow nutes until she is ready for flowering. A description of the problem is, it starts with dark or dead spots on the leaves. Then the leaf slowly starts to yellow out, until the dark spots become dead, pretty soon the leaf becomes pale yellow and starts to dry up and brown and eventually die. IT looks very similar to overwatering or nute burn. But since the problem started before I started flower phase, I ruled out nute burn, and figured overwatering. I have another plant that could go into flower if this one dies, but I vegged this to 2 ft, and was hoping for a bigger yield this time. Any thoughts?
Some variables to consider are : I think I may have excess light. I am using 400 HPS with some reflective paper redirecting rays onto my plants. I have a grow room about 4x4 at the bottom and 7 feet tall. I am hand watering rockwool at the moment until I figure out how to fit all of my equipment in my grow room. I don't have a TDS meter right now so I have no idea what her ppms are. Positive thing is her flower buds are more developed than they were in my first plant at this stage, which is only 6 days into flower.
I just can't keep her fan leaves from dying, perhaps it doesn't even matter.
