PS - check your soil PH and make sure it is correct. It looks like the start of a Ca/Mg issue or a PH issue causing lockout.
@fatneil, Thanks Growmie for the like, your girls have got a good start, but I think MrNObody may be right about PH, check soil run off, or do a slurry with some soil and water you are using and itโll give you some ๐ก. Check the PH of the water being used, and if tap water make sure itโs being dechlorinated long enough. I had a very similar issue early on until I got a very basic PH tester for $20. Good luck Growmie ๐คDonโt hesitate to ask questions, the people here are Awesome ๐
