Spots on leaves and little twisted...Spots started slowly showing when it had a different 600w light, too much heat back then, this started a little "save operation" changed light, made the plants look a bit healthier but now it looks like the spots have spread and also affected the leaves above... Are they healthy?

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?
