Interveinal chlorosis and dead spots on leaves, deficiency?

MrSnoidstarted grow question a month ago

This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Beginning of a calcium (brown spots) and a magnesium (chlorosis) deficiency. Easily solved by adding a cal/mag supplement to your fertilizer line up.

Little browinish/beige dots near leaf veins I noticed some weird little browinish/beige dots near the veins of some leaves, mostly the upper/center ones, those exposed to the light. I checked for bugs everywhere, even with the jewel loupe, and I haven't see one. What can it be? Maybe heat/light stress?

Twisted/mottled growth Not a happy plant, was on a windowsill in 30c back 6 days ago and think the roots were overheated? Transplanted to final pot and have been foliar feeding since but no improvements (gained about 3cm in height!) Found caterpillars yesterday so removed leaves. Will she bounce back?

Damaged leafs Hi guys! I have a flowering Northern Light with several damaged leafs, as you can see on the pictures. Are they deficiencies of some sort? If so, what do you think can be the root cause? I use only filtered water and the RQS easy boost mixed with the soil since the beginning. TY

One plant is looking bad but still doing it good leafs hanging it looks strange If you can see on the picture one plant is looking a little bad. She grows in the length better than the other one but the colors looks a little like yellow or lightgreen and the leaves hanging down and feels hard or raw. But she's still doing it good! Over feeded? To much water?

What does this stress look like? PH lockout? Overwater? Natural Fade?I overwatered. Did 4 litres into the pot. Then did another 1.5L the day after (in a 7Gal cloth pot) I think this caused overwatering toxicity. Does the strees look like: Water Toxicity? PH Lockout? Or fade from entering in the latter half of flower? Buds getting bigger still.

Brown spots on lower leaves Long and short of it is that I'm wondering what's going on with these brown spots on Tiamat. The solution pH has been dropping rapidly, even though the PPM has only very slightly raised (250 - 275 over the past 3 days, whereas pH has shot down from 6.2 to 5.8).
