Leaf problem with Train Wreck Auto

Also, running a 600 watt HID system, MH til flowering, then HPS. My second biggest TWA plant, is bushy, lush beautiful darker green, NO yellowing, watering and nutes, same is the bigger yellow tipped plant. Bigger plant shows female all over the place, 2nd plant shows a few female signs. These two plants look totally different. With a few yellow tips on JHA's, is it a light problem? Nute burn seems unlikely. Confused, naturally, as newbies are, lol. Thx.
 
Hi Mr Red! I'm Blue ... so feel obliged to help one of my "primary" buddies out if possible :D

The cal mag problem is most likely caused by the LED. I say this becuase i have seen the problem countless times and have run LED for years.
You could mix up a foliar spray of epsom salts to help out, or add some cal mag to the waterings.

Mostly i don't get to concerned about it, even though it's very ugly, i can't say it's effected any of the quality of taste .... perhaps yeild is a factor to not running things perfectly, but they always seem to make it to the end and provide enough .... Like champions!

Hope this helps

Blue ^_^With distilled water, how much Cal Mag should I use to address this problem. Just tried 10ml/gallon but don't know what I am doing yet. Thanks. Train Wreck autos started turning orange after about 25 days of flower. Fox Farm soil and 1/2 strength trio of nutes.

:d5:
