Struggling with progress.

Se la terra è secca devi darli più acqua, un consiglio stira le piante e riempie la rete. Poi quando stai per portare a fioritura defoglia gradualmente tutto quello che c'è sotto la rete. Le foglie sono verdi non sembra male. Saluti

Best advice would be to grow in bigger containers. If container seems dry, and when you lift it it is light, you need to water. However when you watered before, you need to water ASAP. Plants in middle flowering can be very thirsty. Water consumption can vary from plant to plant, and be affected by other factor like temps, RH, airflow, distance from light.

IMO you should get used to the weight of your vases, then you can have a more precise idea when and how much to water. Sometimes the fans dry the top soil straight away, but at the bottom of the vase thats a lot of water concentrated, which can cause problems, most comon, root rot. Good luck :)

Plants that size need 3-4 litres per watering.
