Its probably nothing but shes my baby. We call her "the bush"

Soil: Fox farm Ocean forest

Nutes: jacks Classic

Strain: Kings Kush

250w HPS cooltube

Age: about 7-8 weeks

Some slight LST so its gowing at an angle not straight up. 2nd grow


There really only about 2 leaves with spots that i could find. these weren't here 3-4 days ago. this is the worst one. its towards the bottom.

Any ideas?

Seems to be spreading, Checked PH coming out again 6.0

Its happening to older Fan leaves towards the bottom.

i put some dolomite lime when i mixed the soil but i dont think i put enough. I will order some cal-mag asap. do you think i should lightly sprinkle some lime on the top soil and mix the top soil gently?

I will keep checking everyday

I'll keep researching. The light colored veins are concerning.

It looks to me like that you might have spilled something on it. Is that the only spot?

No its not the only spot but its the biggest one,

still getting worse and its looking like the leaves are getting lighter in color. especially the new leaves and shoots.

looking at the chart it really looks like phosphorus

adding cal-mag and increasing nutes to 680 ppm from 350 seemed to have halted the spots. ive just never had a plant this big before so i guess it was starving for nutes. thanks everyone!
