Yellowing lower leaves is normal indoor, even in veg. Outdoors, it happens later. Don't even try to compare plants growing under lights to those grown outside. The growth stages are very different, even with the same strain. It's to do with the distance from the light and the power of the light source. 2 foot away from a bulb is twice as far as 1 foot. 1 hundred million and one foot away from the sun is not twice as far as 1 hundred million foot away. Hope that makes sense. Put it this way, you may scrog a plant under a 600w hps that is 30cm high at flowering, no leaves left, looks like sh1t and puts out 8 oz. You could grow the same plant outside and have a 10ft monster.......that puts out 8 oz. Generally, if a plant dies from bottom to top, it's over-watering. If it dies from top to bottom, it's under-watering. However, ALWAYS expect a plant to lose some leaves (especially fan-leaves) from the bottom. Don't see a few leaves yellowing at the bottom and slow the watering down unless you really think there is a problem.
