HELP!!

1. Is my 300w LED to close ?

2. Is a lil Nute burn okay ? Even though It spread to almost every leave tip ? Or Just I flush it w/ plain water or just know next time not to add the same amount of nutrients on the next watering

Where did you get the led ?

Have you tested it ? It might not be 300w
This makes a difference for the hieght.

Try feeding 3/4 strength next time.
You may be getting burn because your light is so weak and they cant use up the food your giving them.

Where is your grow located ? In your house /shed/ basement.

If their outside your co2 might be very low. If your in an occupid house the co2 is usually pretty good.

How is your temps/humidity/ph this is much more important than how much your overfeeding them

I have two of those 300 watt LEDs. They are 130 actual watts each.

I keep them 10-12'' away from top of plant

Don't flush anything. Just water next time. No nutes.
