I flushed them each twice a couple of weeks ago, and then resumed feeding as normal after they dried out a bit.

E-indoor or outdoor: indoor
E-soil, soilless, coco, aero, or hydroponic: soil
E-specific medium: MG Organic Potting 75/25 with perlite 1 1/2 gallon pots (kind of small I know)
CSL-Soil type/brand: MG Organic (they've been in it since the beginning, I won't use it again, I promise)
SCL-Anything you have added to the soil: Nutes as below
SCLR-Soil or slab runoff pH: high 6s (as per cheap test kit)
E-Water source: alternating b/t distilled and tap (the tap is very hard), figured the hard tap would provide enough cal/mag
E-Source water pH: high 6s
E-Age of plant: about 5 months total, around week 7 in flower
E-Type of fertilizer: Botanicare Pure Blend Pro Bloom 1-4-5 at full strength (has produced minor nute burn on the tips), also molasses with the last 2 feedings
E-Rate of application: full strength (2 tbls per gallon)
E-Lighting source and distance from plant: 150w HPS about 4" (I know that sounds close, but I've seen no indication of heat damage to the tips)
E-Air temperature (both day and night if you are running a dark period): 75-85 during the day, not sure about night time temps, got up over 100 a couple of weeks ago for a few hours.
E-Air % Relative humidity: 52% at the moment
E-Lighting schedule: 12/12
E-Type of ventilation your room has: twin blade window fan blowing up from underneath, only intake/exhaust is from pre-existing cracks and whatnot.

The untopped plant has gone pretty quickly from verdant green to what you see below (acutally i guess the lower leaves have been yellowing for about 2 weeks). The topped plant has been degrading for a while longer. Minor variations because of human error aside, they've been on the same schedule, though the topped one is about 2 weeks older in total age (same time in flower).
Looks good maybe next time you could inoculate your soil with some beneficial micro-organisms ,and I want to get me some root excelerator . I hear that Sweet' from Botanicare is good, and. Liquid karma is great stuff
Things things will help you speed things up, and produce more yeild ,and all together get rid of that yellowing at the end.:jointsmile:
