1st week of 12/12 Leaves yellow (Pics)

I think its an overwatering problem. Will this give me less yield in the long run? Is it worth keeping them or should I start over? They are all about a foot tall.

Any advise would be greatly appriciated

well first of all do not start all over second of all have you been giving them any nutes 3rd of all how often do you water becouse in those pictures the soil looks very dry

I use fox farms entire lineup and I go by their schedule on their website. I feed every other watering. I also have a moisture meter. The top soil looks dry but it is still moist. I water every 3-4 days. I had an overwatering problem when they were young in the veg stage. I transplanted them about a week before I switched to 12 hour cycles. I watered them when I transplanted and the soil was moist before I transplanted so I thought it was still an overwatering problem.

buy looking at them im thinkin its a ph problem you should flush them becouse im thinking you have a nutrient lock on the soil theats causing your plants to starve mainly from nitrogen i would definetly flush them real good and see how they react to it

Those plants look just like mine, but I think I 'm a couple of weeks behind you. I've had some excellent advice suggesting it's a PH imbalance causing the plants to not be able to use some nutrients in the soil. The cause of mine yellowing is a Zinc deficiency from this 'lock out'. Check here https://www.rollitup.org/marijuana-plant-problems/262596-yellowing-leaves-experts-needed.html

I'm afraid to flush because I already have an overwatering problem. I'm going to let it completely dry then I will flush them. I have another strain that I'm growing. I use the same feeding schedule and they look fine. Could one strain be affected differently than the other?
