Indoor Nutrient problems? Over watering?

[trippymike]

Calmag? Whats the problem? This is the middle of the plant. Leaves are starting to droop slighty. I havent watered in a few days.. Is this normal for flowering?

After some thorough research i believe this is nitrogen toxicity. The tips are starting to curl downward. Any advice from here would be great.

what feed and supplements are you using, and have you looked to see what N is in them? Tip claw is usually N-tox,.. but the mid-leaf symptoms look like early P defc, hard to say just yet,....
