Hi Samuel,
The curling and yellowing in your plants are most probably due to a PH unbalance.
Are you watering and feeding them in the correct PH range for soil ?
You can increase a lot your yield if you keep the temps in flowering constantly in the correct warm range. With temps around 10ºC the final yield will be less than half than it should be.
Any improvement you can do in your room settings to improve these variables will produce a very significant improvement in the health, yield and final quality of your indoor flowers.
Hope it helps.
