Cal-mag Deficiency or other issues?

[Mustbob]

Hi everyone,

Seeds: Amnesia haze auto

Medium: soil

Water source: Bottled water (ph:6.9) 1,5L/per day

Flowering stage just started for my girls (42 and 37 days)

I observed some problems with few leaves. I use crushed eggshells mixed with vinegar and epsom salt to avoid calmag issue. Could there be calgmac deficiency or insect issue? I use my balcony for sunlight (8 hours) and supporting with 100w COB leds (12 hours). I would like to hear your valuable suggestions.

Biobizz light mix
Biobizz top max

Have u splashed those leaves it seems like it could be that there are lots of people running bio bizz hopefully they will chime in also it looks like it's the oldest growth so maybe bump feed up all the guys running in say it's hard to give it to much as far as wat I've seen.

It could be because i just observed on the bottom leaves. I will try not to splash biobizz. Thank you for your opinion. By the way how the girls progress according to days i shared? I topped i of them around 15. Days and i didnt topped other one but that one's main cola getting taller, for topping it's late but can fimming be applied?

last twp ics look like physical damage to me, not a defc.... first pic, likely a touch of fungal attack, not uncommon on lowest leaves touching the soil,.. just snip it off at the base!
