To much heat and to much light maybe. It’s light stress/heat burn with a little to much nutrients maybe. Stop using calmag if you do that

Can I use magnesium sulfate foliarly?
Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Yellowish color at the tips and wrinkles
My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

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?

Forbidden runtz excess or deficiency problems autoflower
BAD WEEK! need some help here guys.. Brown / rust spots started to appear on the tips and slowly started yellowing leaves. Im following the master advanced nutrients chart and watering 2 times a week. Last week feed was 20 litres R/O water 80ml bloom A 80ml bloom B 40ml of every additive on the chart 20ml cal meg 30ml phup PH adjusted 6.50 After i started noticing the brown spots / leaves curlin up and stunted growth i skipped a feed and flushed with plain R/O water used 30 litres for 4 auto plants. Yesterday i watered again but cut the nutes in half. 20 litres R/O water 40ml bloom A 40ml bloom B 20ml of every additive on the chart 20ml cal meg 20ml phup PH adjusted 6.50 I still don't know what the problem is, if it is a excess of something or a deficiency..Looks like a cal meg deficiency but ive beed using cal meg since the beginning. Maybe i have excess nutes in the soil and resulted in nutrients lockout of cal meg or something else? since i water twice weekly should i water with nutes always ? The master advanced nutrients chart still sometimes confuses me. Please any help will be appreciated

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!
