Strange leaf shape, who has encountered this and what came out as a result?
1. Am I right that it was just overwatering? 2. Who has experienced the same thing? 3. What are the chances of growing a healthy plant? I appreciate all the responses, this is very important to me, thank you!

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?

Possible deficiency/humidity/pH problem
I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater

What gave this? Light excess or nutrient burn or lack?
I had this symptom from the beginning, stable, I didn't worry too much. What could be the reason? How to avoid this in the next grow. I mean, it's minor, but might be better to attend and unleash a better result. I have this on all buds, on canopy it comes with curly leaves.
