That seemed to work. The newest growth looks good. The cord pulled out of my ppfd meter a couple months ago, and I have been guestimating from previous grows. I need to get off my lazy ass and search for the spec sheet to see which color wire gets soldered where. IF I can find it online.

It was a cheaper meter from China (I'm assuming) but tested against my friends Apogee its accurate enough.

I have a cutting of my last cycles Blue Widow that has been vegging for 6 weeks. I am using an Earthbox with living soil. I have not filled up the resevoir yet because I dont think the plant is big enough to drink 3 gallons of water before it goes anerobic.

The leaf edges have been wonky for the last 3 weeks. I assumed magnesium deficiency and treated with Epson salt foliar spray last week, but the new growth is the same.

Any clue?View attachment 2121079
