What could be causing the appearance of this leaf? The leaves are healthy and don't have any other types of spots apart from that discoloration. It seems to me like a magnesium deficiency, but I'm not sure. Thanks.

It looks like calmag, its not. Chow is right. Is lack of P. With a light touch of calmag. But, p control the movement and so on of other key nutew and if that's of. Well, you just seen a funny by product of both. But it's defo P. Too much purple around those vains. Look at the back of your leafs. If they all purple. It's defo in need of a P injection. Good luck.

The petioles are totally purple, Sensi Grow has 2% phosphorus and I've used it in low doses, so I don't think it's an overfeeding issue... I'll increase the phosphorus dose to see how it reacts.

The plant is in its 6th week of growth and most of the leaves show that appearance. It's grown in All-Mix from Biobizz and I'm using the Sensi range from Advanced Nutrients. The pH is at 6.5 and the EC fluctuates between 1.4 and 1.7 depending on the watering; I usually water them every 2 days and one day a week I water only with enzymes.

My leaf deficiency chart says its a phosphorous deficiency. My gut feeling says its a lockout from over feeding. My experience says I need more information to make a proper diagnosis What medium are you growing in, how much, what stage is the plant, where on the plant is this happening. PH levels, PPM/EC. feeding schedule with how much.

Yes, it really looks like a magnesium deficiency! Before fertilizing it, though, check the pH of both the water you're using and the runoff, as it might be a pH issue that you can solve easily :) If it's fine, go ahead with magnesium (or cal-mag) and you'll be all set! :) Happy growing
