Switching to LED - Change nutrients or quantities?

[Ciccio13]

I'm switching over to LED from HID. To I need to adjust the quantities of nutrients, water, routine, etc...?

Good question. Im going to listen in on this. Interested in opinions or facts that people have.

There's many variables.

Under my Mars I saw an increased need for Calcium and Magnesium

When I went to way more intense cobs I saw a dramatic increase in the uptake of water and nutrients.

I think it depends on the plant and how intense your light is.

This is one of my questions I originally started growing with 1000 watt HPS and now I'm starting all over with full spec. Leds and T5

Great.

I run led cobs that I put togethor (diy)

I find I my plants grow faster than under HPS so they use more water and nutrients

I am also funding the plants respond better to my leds at 2'-3' versus as close as I could get with the hps.

Plants under LED do use more magnesium and calcium.

As for other nute uptake differences best answer is to watch the leaves and adjust as you would with HID. LEDs vary. You may need to reduce nutes slightly if LED's less bright, but otherwise watering/feeding routine should be the same.
