That looks either like wind burn or light burn...... if you have a fan directly on the plant, then there is your answer, back that off..... second if you dont have a fan blowing direct, then you have to watch your light levels cause this would then be a light issue. This isnt a deficiency.

Much appreciated that’s is most likely going to be the issue! My fan is close! And I have a 250MH about 20” away

naaaa sorry guys thats a mag issue that all day long that! damage done on cellular level with cal/ mag issues wont repair

you have gave them a foliar spray of epsom salts /calmag.

4.5litres warm water, table spoon of epsom mix well. take out a litre an lash rest down sink. add2-4ml calmag to that litre and give them foliar spray

you need be doing this every 10 days depending how soft your water is. its a must in coco for me with a background of 0.1/0.2, my water super soft

and just for confirmation look here to post #8 https://www.thctalk.com/cannabis-foru...iciency-thread that backs up my assumption

Thank joker!

I have gave them a cal-mag spray at like 1ml per litre

Do I need to do both cal-mag and Epsom salts? If so where do I get Epsom salts from?

probs not enough, dont expect the spray to repair the leaf damage mate coz it wont but making sure new growth is what be important.

yes mate the extra mag from the epsom helps the uptake of cal more and also will give them a greener lush look.

4.5litres warm water, table spoon of epsom mix well. take out a litre an lash rest down sink. add2-4ml calmag to that litre and give them foliar spray, raise lights high as poss till they dry, do this when lights are on also - thats how you do it mate simple stuff. boots sell it about 5quid big bag last you forever, think mine is called westlabs bath salts

windburn or heat stress will cause edges to curl an cup and theres none of that going on either

also thats a perfect height for your 250 bulb i go 15inch with fan blowing in between, if your light were to close it would be causing bleeching
