I just picked up
I have a good friend with one an hlg 350R and he hates it. He says his sf4000 kills it fwiw.
That said, I still rock 1ks just DE's now and have no beef in the led game.
That's why fems and autos seeds dominate the market now. Its also why guys like me, up pot, don't want to waste time energy and money on males unless he's a stud.
Just because his e.c is good doesn't mean the meter is off or the plant can be nitro sensitive such as a bunch of blue strains, or his coco doesn't have have some salt build up in his coco. There's more examples to such as grower error.
E.C isn't everything. Reading that plant says its too much...
