Yesterday before watering my plants they looked normal. Now they developed these goldish yellow spots on some leaves overnight. Can anyone tell me what could make this happen? Ca/mg deficiency maybe?

Yea I also have a dimable 600w hps but I use 250w for veg and 600w for bloom last crop I did with 400w bloom cause of higher temp outside. I also have a cooltube and 400m3/h ventilation machine (cant remember english name for it thats why I say ventilation machine

Yes I will try mh bulb for veg next time this time only hps :)

Yea I need to check the temp if I cant controll it I try without the tent... the rooms walls are covered with mylar anyway

Okay thanks for the tip! I can also take the tent away and use the room it is in its bigger space but harder to controll the air ventilation

Thank you! Yea I will try to find one :)

And now that weather gets colder outside the temp wont be a problem

Yep I have tried the 600w to test the heat and its just a very little too high but with proper air conditipning I can keep the temp at the right amount cause I have a air vent that goes straight outside from the room where the tent is :)

I am only using a 100cmx100cm grow tent (1mx1m) so I guess then ill go with 250w hps for veg and 600w for bloom :)

Hello people. I was wondering is it beneficial to use 400/600w hps in the vegetative phase? Or is it just a waste of energy? Last crop I did 250w hps in veg and 400w hps in bloom. Now I am wondering should I increase the vegetative phase wattage or is it just a waste of energy? I will do bloom...

Do you guys have any advice about my fans... should I put the fans to blow at the top of my plants (to avoid hotspots and strenghten stem) or at the grow light to blow the heat upwards? (My active carbon filter is sucking air from the top of the tent)?
