Meter is 4sure calibrated. I do that every other week as maintance on my blue lab. Also did it right b4 all this went in. The yellow leaves are the ones that were there while the cuts were rooting. All the new growth has 0 burn on them.
I am definitely going to drop back down to 200-250 ppm though and see what happens. Like
@rkymtnman said it cant hurt anything to watch what they do at it again.
I have to build a room to just clone myself in lol. These are what they all started out as 14 days ago.... they took so long to root that they were in some rough shape. The way the new growth is stacking is what makes me think reveg and a few of them do have pistol like hairs. But just a few, its fucked up honestly lmao. Im pretty sure after this run im swapping back over to rockwool on tables with an auto feeder. My veg time in that is almost identical to this rdwc and its soooo much less time work and worry.
