my thoughts on flushing solution....
I have really good tap water
anywhere from 5-20ppm is what my tap water reads. Other than that, I dont bother with any flushing solutions.
About taking off your fan leaves...
I just did a blog post on defoliation earlier in the week and the myth behind it.
It can be alright in flower, but taking leaves off puts a bit of stress on the plant.. the more leaves you take, the more stress you put on the plant. instead, try just tucking leaves out of the way.. bend them or tie them even. Plants use their leaves for photosynthesis, which is pretty important when you are growing tasty buds on your plant.
taking off branches that will never make it to the canopy is more than okay, like you mentioned you did. These branches take energy away from growing big main colas, so take a couple at a time, never a whole bunch, or you will stall growth/bud production. One or two every few days throughout flower wont stall your plant out at all, and it will focus its energy on those main colas above the SCrog
Some people take off the lower fan leaves because they think they aren't getting any light, and therefore aren't useful. But these leaves store useful energy for flowering, in the form of carbs and sugars and other stored micronutrients that the plant uses up as your nutrient recipe changes in flowering.
Stress adds time to flowering as well, so if you are on a schedule, like some people are, then you dont want to stall your plant out while it heals.
Just some food for thought. Your Papaya looks lovely under that 600w HPS!!! It has me itching to pop my papaya's!!
I unfortunately just have too much going already!!
