[Mr.furley]

Hey poriya,
can you tell us a little about your grow, water schedule, nutes you give and how often, what's your PH levels, and your grow medium.

[Canuck147]

Yeah what Mr Furley said.

[St.buds]

Just by looking at the picture I would say lower nutes and adjust ph to 6 do a flush first

[stevenics]

first pic looks like possible ph problem in the soil, test your runoff to see if the ph in the soil is out of whack . the second pic looks like nutrient burn.
