Brown spots on the leaves

You got some PH issue lock on some nutes , ,and DM means direct message that little arrow in right hand corner where you can communicate with other growmies .👍🏼

Hello Gottagrowsometime. I keep giving the same fertilizer, it's really in milliliters. I don't know what DM means. The substrate is different and is only lightly fertilized, the ph substrate is 6. When I moved them, I immediately watered them with fertilizer.

Hi buddy, need some more info please. Are those the real ml/l or are they adjusted? When you uppotted what did you do, did you put into the same kind of mix and use the same nutes for the first day or 2 and same strength 2 min shock? Or did u introduce a new nute when u changed pot or a new substrate or lvl of ml/l. Very strange, as that looks like it's been progressive and not just an over night thing. U can DM me the info or add it here for others to make a judgement good luck pal.

Looks like a ph change that caused a lock out.
