Looks like magnesium deficiency but need more
info...

7 week old plants
Indoor grow
T5 fluorescent at first
LED for last 3 weeks
Good growth
3 part nutrients (emerald harvest) and calmag
Water 2-3 times a week
Nutes and calmag once a week

I gave them nutrients/calmag last Saturday and noticed these leaves on sunday/Monday. I added more calmag on Tuesday with my normal watering. It seems a bit worse now!

 

[Anuenki]

Well if it isnt mag then since it is lower leaves i would say nitrogen...

Height of light?

It's a 1200watt and I have it like 30 inches above the plants. I tried a bit lower but the top leaves curled up a bit so I moved it back up. Should I try closer for a few days and see if it helps?
thanks for the responses guys.

 

[Anuenki]

No if you moved it down and saw a negative response, don’t put it down again until flower, i am assuming you are still in veg?

 

[Floody709]

Nitrogen seems to make sense now that I have searched it and seen the pictures!! But should my emerald harvest nutes help with that?
Or do you thi k these girls need more nutes than I am giving?

Don't move it down, try moving it higher. My veg. lights site say 36" for my 4wk old plants.

 

[Floody709]

Yes they are in veg. I wont move the light down. Thanks for the help with the light!!
