AsNoriuanswered grow question a year ago You dont flush in soil !!! FACT !!!
No feeding for 3-4 waterings, water with run off, load good ph, 6.3 is best in soil. Run off about 10-20% of total amount in, water slowly, for better saturation, so have 5 min intervals.
On third watering you can add calmag, max 0.5 ml/L to most brands.
If she sarts to drink regulary, then you can return to feeding, think by that time you have to use only bloom nutes, no Nitrogen needed.
