I’d just use EC, they both tell you the same thing. EC is more universal.

Check out blue lab. I’m about to pick up their ec pen. They have some really nice stuffMy meter reads 700 scale ppm unfortunately
Yeah your at 1.171 ECSo I just recorded it again. it says 1171 for EC and 585 for PPM but that chart up there has decimals.
is my reading closest to the 1.1 EC and 550 PPM line under Hanna?
still trying to wrap my head around this, been rummaging through old threads
Dome off, toothpick planted.You can lose the dome on the seedling it doesn't need one unless your Rh is really low in the room your growing her in. The reason she fell over is because she is stretching you could just prop her up with a toothpick to help support her. Get her closer to the light if you can and get a fan moving air around her but not directly on her. How often are you watering the lst plant?
have you ever used gro-blocks? many companies use big 12 in gro-blocks that top feed DWC for commercial use. I was excited when they came in my kit but now I'm not too sure.I don’t care for rockwool, it retains water so well it’s hard to judge when they need watering.
Ya just feed when the pot feels light when you pick it up that's the easiest way to tell when it needs more water. Judging by the pic of the lst plant it kinda looks like to much Nitrogen because the leaves are clawing and it looks pretty dark green. I don't use any thing like blood meal not even sure how to advise you how to use it. Maybe bottled nutes might be the way to go.Dome off, toothpick planted.
I was watering once a week and feeding every other watering but I should probably just feed every time they get dry right?
