Plants are 3.5 weeks old (in veg), bubble gum strain.
The room tends to stay in the low 80s and into the high 70s at night. Humidity is typically around 50%
Under a 400W MH 24/0 in soil which is local hydro shops "pro mix" plus about 33% (by volume) perlite.
Plants are given a half gallon of water twice a week. 1 time is the botanicare directions found here -> with ph'd and the other is ph'd water with 10ml cal-mag per gallon.
According to the soil PH meter (the 2 probe basic one) my PH is in the mid 6's for the soil.
Im thinking nute deficency, but I am having issues finding a pic that matches (i am very poor at diagnosing nute deficiencies)
There are pictures of 2 plants attached.
Thank you in advance for any sugestions/help
