Hi guys,
This is my first setup and grow so please be kind
My setup:
- 1x1x2m tent
- 600w dual spec HPS with reflector
- 6inch fan
- Black Orchid Mixed-flo 100 filter kit (exhaust system)
- Second in-line fan to pump fresh air in
I've set up the tent and put in my seedlings in there on the 14th of March. I'm running a 20/4 cycle since then.
Today I have noticed that the leaves are starting to look a bit weird, they're shiny, some of the leaves have yellow burns at the end of them, can be noticed once zoomed in on picture. I have been using 6.5 ph water to water them. I have given them 0 nutrients as they're still very young. Can any one help me with the problem? I think it could be heat or light problem but I'm unsure, the temperatures inside get roughly to 32-33 degrees C. With the fan 6 inch fan switched on, I measure around 28 degree C due to the wind. Out of 4 plants only 2 seem to be affected so far.
Thank you
