How many watering should I do per plant? Not sure ...

Hello ! The best way to know when to water is to lift the pot when it's dry , water it then lift the pot ! When the pot will change weight to a lighter one then it is time to water and your plants will thank you. Your leaves looks ok , maybe a slight overfeeding due to the nutrients already in the soil but nothing to worry about. If takes photos without your light on we will be able to see the true colours of your plants then to find the true excess/def ! Hope it will help you😁👍

Je moet ongeveer eens in de 5 dagen water geven. Begin met een glas water, ongeveer 200 cc, wanneer de grond weer droog is, geef je water. Wanneer het tijdsbestek om te drogen na het water geven 2 dagen is, verdubbel dan de hoeveelheid water. Spoel en herhaal.
