Hey guys this is my first grow so I thought I'd experience a few minor problems ( I hope there minor ). I'm on week 2.5 of my grow and have started experience nutrient burn on some of my leaves, first question, should I be feeding it less nutrients? My feeding schedule goes something like this, 5ml canna a+b per 10litres, 5ml of magical, 5ml of cannazym, 5ml of rhizotonic, 2ml of ph- to get the ph from neural to approx 6-6.5. My water tank is reading 400ppm, is this top high for these little ones? I havnt got major nute burn as you can see but surely my plants should be looking healthy there sop young?? I'm going to just feed it water for a few feeds as I feel a flush is abit OTT at this stage? Temps are 30 lights on, 21 degrees lights off. Help would be appreciated. Many thanks
