Medium Flushing Advise Needed

[Litemup]

I'm growing 12 females and due to space & location & my illness (they are in 3 & 5 gal. containers) I have not been able to flush my grow medium.
I am 4 weeks into flowering & as yet have observed no indication of "lock-up".
What I have done for this indoor grow is to use organic fish & seaweed fertilizer (with 30ml/gal peroxide(3%)) at 1/2 strength every watering, plus 1/2 strength chem fertilizer for each stage every 2-3 waterings, with pure water(1gal each) at least once a week.
Will this work OK?
can anyone help me with ideas to flush that do not include lifting and moving plants to where all that water can drain?

Generally you would not need to flush the medium{soil},unless you see visible signs of burnt or curling leafs,slow growth,ect,ect.Most people flush during a grow-cycle, when they know they have somehow screwed-up, and are trying to save the plants.A good liberal watering between 'Fert' applications is all thats really needed.All that hydrogen peroxide is probably doing more harm than good.I use a system I call ''Double Watering''.I always give the plants straight water first..either from the top soil or ''Bottom watering''i.e Fill the drip tray full of water..let the plant drink.After 20-30 min. I will then apply my Liquid fert/water mix.Plants that are sitting in dry soil and or In need of water..are far more suceptable to fert burn from a strong Nutrient mix..especially Chemical ferts.It's all about plant Osmotic pressure,blah,blah..don't really wanna get into all that..AnyHoo, hope this helps...Keep it simple..keep it green!!

This is a K+ point skunkenstein. Dry plants can show overfert symptoms with very tolerable, normal PPM's. If the plant is dry, give it a bit of water before you fertilize.
