Ok cool. My light is 14” from plants. None are “burned” that I can see. All are medium green and they just seem to be slow or not growing. Haven’t used any nutrients at this point. When is a good time to use your first nutrients? I am a newbie but want to succeed. Thanks man!
Nutrients: You should feed Autoflowers either 1/4 to 1/2 the Manufacturer's recommended concentration. Move up to 1/2 their recommended amount, as your plants tolerate it. With some plants, "Less Is More" - especially Autoflowers. Only proceed to Full Strength with great caution, monitoring your plants closely, for signs of toxicity. WAIT A FEW WEEKS, OR EVEN A MONTH, to begin. Your Autos should be pre-flowering then. That's when they'll really need it.
I don't know what kind of nutes you're using, but for instance:
Advanced Nutrients is a 3-part fertilizer...equal parts (1-1-1) Micro, Grow, and Bloom. It has worked great for me, but their online directions specify that for Autoflowers, you should disregard the Micro and the Grow completely, and use ONLY the Bloom portion.....all the way from Flower to Harvest. I had to re-read that a few times, myself. FOLLOW DIRECTIONS...or Forfeit. It's a lot harder to take an excess OUT, than to put a little more IN, if you didn't use enough.
