Hi guys. So first time growing such powerful LED, and must be some problems bcs of this. Looks like Calcium or Magnesium but never had that before. Light is MarsHydro FC-E 6500 730W. Is like 60 cm away in 120x120 tent and not even on 100%. I also feed them a bit less than normally, can it be just not enough nutrients ?

Biogrow from Biobizz, root stimulator from BB at the beginning. Now i added CalMag for 2 times. Ph is ok, and water temperature too.

From what i can see,, i would guess from the light color of the plants that they need more food and far as leaf damage, it kind of looks like over watering.. and it does look like a cal/mag problom.. are you using r.o. or tap(well or city)..

I use different water as before (location), but it's tap water on the country land and sitting for 2,3 days before adding and watering. I did clean the bottom 3 days ago, but i don't think it would be stress on the leaves like that. They were dry before watering so not sure... I will give them more food and keep adding CalMag. Thank you.

If you are using ground well water i wouldnt keep giving them cal/mag.. the tap should have enough calcium.. maybe give them a epsom foliar spray and no more cal/mag

Ok. Bcs i never used CalMag before and never had this, so i thought maybe it's those new LED lights who need more CalMag. Need to check this epsom foliar spray if i get it here in Europe.

Use the same light and at this time I am in veg.
Every plants a bit different in how much it can take and thrive.
For eg the plants I have now run best at 250 ppfd as say 300 were they will tinge yellow .

That would be 84cm away at 45-50%.

Enjoy and good luck with your grow.

I did something similar with my FC6500. OP never said what % he's running at, just "not even 100%." I think I ran mine at 40%, 40 inches....the plants grew like crazy.
