What's the problem with these leaves?

Can anyone tell me what the problem with these leaves are?

These plants have experienced a different leaf problem before which was light burn, this is definitely not the same...

pH is 6.9 in the soil, temperature is running about 27/29 celcius mostly, humidity between 50% and 65%.

The leaves have shown these spots for about 1-2 weeks, have had a little bit of miracle gro occasionally with watering.

my vote is mild nute burn. Mg def typically has more pronounced chlorosis. Water with plain water for a few days...
cheers 'neer
 
Plants look ok
U grow outdoors?
If u think it's a Mg def add Epsom salts. 1tsp/gal water. Every third watering. Or get cal/mag from a hydro store.
 
The grow is indoors under T5s, kinda leaning towards mild nute burn with cannabineer since it hasn't got worse for a few days
