not 100% sure mate, some leaves look very dark in those pics, maybe nitrogen toxicity, hope you get it sorted, goodluck.

That is exactly what I thought about. But it`s rather strange to me.
I did`t use any fertilizers during vega (4 weeks). And plagron that I use is for flowering: mostly P and K. It`s usage 5 ml per liter. I use 1 ml per liter just to don`t burn the plant.

Will it be good if I flush the soil with water mixed with ph down liquid upto 6,5?
Or it`s better flush with mild complete fertilizer?
May be there are any other suggestions?

water with just ph'd water and let about 25% run off, collect the run off water and check the ph of run off
