Hi Lost you shouldn't have any issues until the plants start to flower and some times you wont have issues on some plants weeks into flower some half way threw flower and in some plants even weeks before harvest.
I have never seen it in veg only in flower.
You can not pre determine what a heavy sativa hybrid plant will need in flower you just need to watch them and dial / tune each plant in but once you do its easy you know exactly what that plant needs as far as feeding in flower.
I have never seen this in Sativa plants that i grew directly into the ground.
Yours turned out better than my last NH did but I was also feeding them the same as indica heavy hybrids. I've learned a great deal over the last 2 years dealing with soil but just had to give them a go in my old setup to see what happens. Maybe it will work out maybe not but I won't know if I don't try. Have a great weekend everyone!
