So, I've looked at your diary.
You're using soil
So, no you never flush sol unless there's something seriously wrong with its ph or overfed and even then, I normally fix by just doing 3-4 controlled ph feeds. Soil is very easy to fix.
But, you don't flush it. Especially when you've weeks left in flowering pal
So, you wanna soft flush. This actually doesn't consist of any water coming out the bottom and been thrown away. It just means, you're letting the plant eat what's left in the pot from the weeks Core NPK bloom feeds
450 or so ppm once or twice every week. Depending how big your plant is, mineral nutrients organic nutrients last longer in pots, mineral nutrients need follow up feeds more so. But in general, organic r not.
Feed, water, water (can be an enzyme or a non NPK nutrient, like a root stim or light calmag/Epsom salt feed). And only if the plant needs it. Give another feed. But, feeds shouldn't be within 4+ days of each other. There's no need. As I said. There's so many stims, Bloom stims that have no core NPK ppm but have a big bacteria ppm which can be given in ernest to a soil plant. They love all that.
Sugars/Resin enhancers etc also.
