Hello! this is my first grow, growing two autos from white label NL and white diesel haze
the problem is mostly on the diesel the one on the pics on the upper plant

i am on day 42 from seed, soil is biobizz all mix fert biobizz grow bloom top max
feeding every other watering 30% less than biobizz chart says

it looks like light burn but i only use 220cfl total 2inches from the plant i moved it a bit higher now

i dont adjust ph using tap water which is not hard and ph about 7

what do you think guys??

Nute burn. Some plants just aren't heavy feeders

Are you using any nutrients with the soil.

Also you said you are watering it 30% less the recommended? How dry is the soil?

i am using biobizz nutrients feeding with every other wattering when top soil is dry
which is every other day my average temps are 28-30c
and using a bit less than biobizz chart recomends

another think is that plant have A LOT amper pistils compared to the northen lights wich is
full white... its sativa its supposed to take more time to ripen compered to the NL right?
