Here are pics. The strain is White Widow/Northern Lights in modified Moonshineman soil mix (FFOF, FF Red bag planting mix, Light Warrior, and 40% chunky perlite) and are beginning their 5th week of flower.

The nutes have been: Tiger Bloom (1tsp. per gallon one feeding so far), Big Bloom (2TBS/gal, fed once) Liquid Karma (1tsp/gal fed every other watering all through veg and flower), and Cl Mag+ (every other watering 1tsp/gal). Nute water is always PHed to 6.4-6.5. Temps are in the mid 70s and humidity is now 30 %, but has been higher to help battle spider mites. The last two weeks have been been bad with the mites and I have had to spray neem (which burned all of the pistils).

Is this some king of fungus ? It is showing itself on the new undergrowth in addition to the older fan leaves.
