Hi all, I am having some problems with identifying nutrient deficiency and would appreciate some help. My hunch is that it is a magneesium deficiency but i don't want to jump to conclusions and give plants something it doesn't need. Pictures attached below. Thanks all in advance for any help.

More likely potassium deficiency. What have you fed? And is this under an LED before we go further? If so how far away

Hey thanks for the reply, this is under metal halide and honestly I havent actualy fed it any nutrients yet, the pots havent seemed to dry up since I put the seeds in the soil and so im only just going to feed them today. Im using NPK industries RAW nutrients so i will be mixing thr nutrients myself according to thier charts. It would make sense thst pottasium could be deficient as the soil was a light mix soil so maybe it does not have much pottasium in it?

No to light bleaching, careful on the "mixing the nutrients myself" and go with your 'hunch'.
When I said mixing myself I more meant that the nutrients are each in its own packet but I will be following the chart and and mixing them accordingly im not that advanced yet lol. I will probably start at quater strength. Thanks for the response.
