White tips on lower part leafs - Overwatering or deficiency?
Duckeedstarted grow question 18 days ago
I've had this one for about 3 months, it's on pre-flowering stage kinda earlier - intended, small space - with LED lights (not sure about lumens, around 75w) and mindflower nutrients twice a week (1L container 200ml week irrigation)
Sorry for the english, i'm not native

Hard to tell, but I can't see anything. Maybe water spots or just dirt.
If you see somethings crawling or like freckled spots, that would be a sign, but right now, there is nothing 👍

I see no white spots. Maybe its leftovers residue from water or feed after drying out ?
Burned tips signs of potash or nitrogen, here you have clawed up leaves a bit too, so its nitrogen toxicity, slow down with N part in feeds.
200 ml for week looks not enough. Underwatering can cause salt build up. You need more saturation, from my runs in small pots would say you need double of that, not in one go, eveey 3 days or so 200-300 ml
