Problem in some lower leaves

Hello dear comunnity

I found this weird thing on some of my lower leaves. I am growing indoors under 400w spider 9 cob led, strain Glueberry OG from Dutch Passion, 3 weeks in veg, the medium is soil (biobizz light mix). Nutrients are Cal max from Grotek until 0.4 EC then Bloom stimulator and organic growth from the brand BAC following their online organic nutes calculator. Any ideas? new shots are doing fine. Thank you!

Going off advice I received for myself in a similar situation, it is probably over watering and/or lack of proper air flow in the pots. I see droopy leaves and a phosphorus deficiency, which is more likely due to the roots conditions rather than lack of phosphorus in your soil. @Onironauta20 I doubt it is light burn if its only on the lower leaves.

How long has it been like this and are there anything else going on i.e. yellowing of leaves, yellow spots?
Is this the only leaf?
