Hi growers, I’m looking for help with my plants. The leaves have started to burn. They’re in the vegetative stage and are 43 days old. What do you think could be happening?

It looks like a classic magnesium deficiency but it could be from many other things also. Without a bit more detail you’ll get a bunch of educated guesses. Ph can cause a lot of issues with nutrient deficiencies.

What nutrients are you using, and how often @ what strength? What pH are you watering at? Are you checking ec? Are you running organic or synthetic? Lastly what medium are you growing in? Answers to these will help us all give you a better answers. It does appear to be a magnesium deficiency the question is why. Is the pH locking out mag or is it lacking in its feeding schedule?

Information on fertilizing – how much, how often, with what, and pH values – would already be useful for identifying the causes. Everything else is just guesswork.

In addition to BluntForceTrauma’s questions, check the runoff ec as well. If it’s >150ppm more than the ec of your nutrient solution that will also lock out nutes. That applies if you’re using coco, not sure about soils.
