Indicas are always dark green...not that I could tell with the lighting in the pic...the taco shape of the leaves is a magnesium deff...use a bit of epsom salts to fix that and if you run her again hit her with 5ml per gallon of calmag up to week four of flower.

End your using soil and soiless mix together....with soiless you want to shoot for 5.8 ph......after two weeks and soil will have no nutrients in it. If you are using dol lime it will buffer anyways...your pretty much running soiless though and id feed at 5.8

Check this for nutrient uptake and availability
