I would usually follow Rusty's advice if he dropped in on me, and I'm not being contradictory here. Did your bloom enhancer contain a significant amount of N? I only ask because I have had N overdose in flowering on a couple plants and that is exactly what they did. All the leaves near the tops bent down and curled under.

It makes sense to me since N is a mobile nute it can effect the tops without getting to the older growth.

Using that MG soil, you may need to flush a little more often, and be careful using any additives. MG doesn't really play too well with others (it's like plant crack) and the nutes it contains are usually designed to last up to 3 months.

Just thought another perspective would be applicable here.

And the top 2 main stems leaves were wilting something bad and clawing even worse. 2 days ago I used some bud enhancer. And I didn't measure and I am pretty sure i used to much. I have been using this stuff for about 3 weeks as my plants started flowering about 4 weeks ago. Untill now I haven't had any problems other then its not working like i thought it would. I am using a 150w HPS. In the last 4 weeks it has grown about 20 inches. I flushed my Rating: 5
