Lockout in my opinion. If it’s getting worse you may want to considering doing a flush with just straight water. Definitely do not add more nutes

Yeah i havent fed anymore nutes. just watered heavy worried a little because i added a little dolomite when i mixed my soil and ph seems to be creeping up like 7.3 now

on your next watering ph down lower than usually maybe like 6.5 to help bring the soil’s PH down. Don’t freak out too much yet I’ve seen much worse lol

Not freaking to much i have been bringing ph in water down to like 6 but just looking for other opinions i do know after reading a little more i will not add lime to my mix next time. they seems to be growing fairly good but wasnt sure if they should be better

New growth looks pretty good but if you're in soil, make sure you let them dry until the pots are light. They look a little wet to me.

the soil is actually a mix of soil coco compost peat and perlite

What's your pH?

Those leaves look like a magnesium problem straight out of a book. If your feeding calmag already then your pH is probably off and the roots can't uptake the magnesium

Some people can make it work i guess, but mixing coco and soil and other soilless mediums is not a good idea imo. Coco and other non soil mediums(hydro) like a ph of 5.8 to 6.2 and i find coco is perfect at 6.0. Soil likes anywhere from 6.5 to 6.8 from the good usesrs that i see using them(i do not grow soils). Mixing them means either pleasing 1 medium and neglecting the other or going 6.5 and they will absorb some of the needed nutrients but not all because the coco and soil will be out of the proper range. You should stick to 1 grow medium untill you learn it. Good luck with the grow.
