very true, nice killer.... to which is my advice need to flush feed until plant is finished,
when this happens due to heat,water,temp stress and container size, these conditions exist.
to ensure that minimal root rot and newt uptake does not halt due to conditions in pot.

I don't like to root bound my plants but i do use tech in my veg room to control population.
i also use the tech of heat,water,temp stress to find x-fem.
i particularly like the uptake time with the bamboo stems its amazing once tech developed
its easy to train plants to immediately take up newts.

always trying........ NF
