Are they getting cal mag?

You have a lot of roots in the pots now taking up space. If they are drinking that much they are healthy. Slow watering is a good thing! How far away are the cobs?

Distance between plants 25cm

That's about 10 inches and really too close to the tops for most cobs. Can u raise them any?

Only Epson salt and dolomite lime

Have you posted in the infirmary? Too much lime can cause issues. But that is past my ability to help.

I think I know what the problem is and where it comes from. I test the Ph pen I have bought with new Ph solution to know if the Ph from the pen different and yes the Ph from the solution is not 6.6 it is 6.3 maybe to low??? My tap water has a pH of 7.0 bevor I test the Ph pen the Ph from tap water was 8.0 so 1.0ph wrong that's not good..... Next I test the runoff pH I think it is below 6.3 maybe 6.0 than I think we know where the deficiency comes from... What you think?

Could definitely be the problem. Do you have another way to test oh? A different pen?

why so close with your led? 25cm something like 9.5inches? that seems awful close for cobs.. you will not get much stretch from the plant keeping lights to close it can actually hold them back... Have ya calibrated your ph pen? that .3 difference you mentioned isn't much... what is your medium? I also see something about lime? they been pre-treated with lime or your giving that? I see also Epsom as foliar? at what mixture?

I calibrate the pen many times and the test is the same... Tap Water PH is 6.8 (perfekt) but without nutrients water with nutrients dosage 6.0-6.2. Water run off 6.1. I think that is the problem! My research give me the same answer PH in soil below 6.2 give a lockout and phosphorus are not available and maybe that's why also cal/mg? I bought a bottle PH Up I hope the Harvest is not damaged from that deficiency?

Distance to canopy in vege 40cm only flower distance is closer to 30cm main top 25cm but I think that is not the problem.

Too much lime can cause problems, the cobs are way too close in my opinion and resemble deficiency as well. I would raise the lights and Do a flush
