-Strain and age
-Climate: night and day ambient T and RH%; res' temperatures; any extremes in T/RH% exposure
- Light used: HID, LED, COB, combo of,... wattage; light cycle hours (20/4, 18/6 , etc.); distance to tops....

Yes please fill out the form so we can get a better picture.
Im gonna go ahead and call this one though.. that is classic magnesium deficiecy.
Interveinal chlorosis gives it away, and at that stage in any plants life there shouldnt be much more going on under normal conditions.
Most will recommend giving a proper dose of cal/mag. I run a calcium based nute line so personally i use epsom salt for my magnesium source (dollar store stuff works great!).

If its coco, which it looks that way.. i think youll be wanting to incorporate the cal/mag in your regimen from start to flush. Im not a coco guy, my soil is hybrid so maybe others can chime in too.

Happy growing!

Thank you for the help. How much epson salt per liter or gallon should I use?

Edit, found a resource. Thanks again.

4T/gal? That's a lot unless Gaia is very mild stuff,..regardless, in coco you need to monitor the ppm's and pH going in, and test the 15-20+% run-off going out... coco cannot be treated and run like true soil, it's a recipe for shit going sideways.... with no ppm, pH info, it's hard to say exactly what's wrong and treat it properly... That said, she looks lightly nute cooked to me, pH might be off as well... around 6.0 for coco is best...
