Hey, I’d like to get your opinion. What do you think this discoloration is due to? Knowing that it’s been like this since almost the very beginning and it’s getting exactly the same care as its sister... a deficiency in calcium, magnesium, zinc....??! Thanks to you, GD growers!

That looks like magnesium deficiency. But also from the " blisters " I think it may be due to ph issue. Probably due to salts build up. Flush the soil then add fresh nutes with correct ph. Might take a bit for the plant to recover. Good luck and nice looking plants.

Hi mate, by the look of the leaves I would say its a magnesium deficiency. A wee dose of epsom salts, about 1/4 tsp to 1 Ltr of water. Either apply when watering or as a foliar spray when lights go out. Other than that its the obvious; PH, PPM etc... I hope this helps

If the others are getting the same nutes as this one without issues I would check the soil pH/ppm of that one before chasing deficiencies.
