grey spots on leafs

hi guys ive got grey spots on my leafs. currently 10 days into 12/12
got 6 dinfem og kush. had a bit of heat issues but thats sorted. any ideas guys on the grey
spots on the shade leafs. cheers guys peace!! soz for hps being on

Really cant see much under the HPS.... Think i see some crispy tips tho are u sure ur not overfeeding?

im currently useing advanced nutrients at half strength had a bit of heat issues at the begining plus had hood hung too low
to canopy. crisped a few top leafs but raised hood and added a heat shield. you think i should knock back a bit on the nutes

looks like you have hps syndrome

hi sunni wot do you mean by hps syndrome. do you mean coz i have posted pic when hps light is on
i apologize for hps being on but its the only pic i have.

everyones going to ask for natural light photos it is preferred and an actual photo of the leaves would be helpful

ok sunni i get some posted as soon as i can cheers
