So it’s on me for not paying more attention I let these lings this round get very leggy as you can see from the photo. Decided to whip out the meter to make sure they’re getting proper ppfd this time around and now under my mammoth 8 bar so no fall off on the edges will be happening. Not a major… ladies will bounce back in their new shoes. Also started a few more beans just because. Any way I’m rambling.
P.s. calibrate your ph meters! I done f*cked up haha
