Perlite Hempys should never get plain water, except to flush. Water, water, feed rotation is only for soil growers. You also need to find out exactly how strong your nutrients are. an Ec/PPM meter is a must.

to me it looks like starving for potassium, probably phosphorous too. My guess is this turned bad after week2 of flower.

It's definitely the plain water you're giving them. That washes out nutrients in varying amounts. No bueno.

I don't run hempys but in my flood and drain I feed as high as 2EC in flower 1400ppm @700 scale and never feed lower than 1200ppm in veg or flower. Can't see why hempys should be any different just less feedings as I flood 3x a day.
