First pic looks like light/heat stress with minor nuturent burn, but the burn looks like it was from the week prior. keep an eye on new growth tips if they keep burning then you are feeding to much. Humidity is a little high so she might not be transpiring correctly. Second pic looks like a lack of cal mag. check your
ph and make sure its within range. if it looks correct the I would say all some cal-mag nect feeding.

Your labels are suggesting 2.4 and 3.0 EC (1200-1500ppm holy shit, batman!)... This is almost certainly lockout if you are following those instructions. That's even higher than what fox farm suggests with instructions, lol
I would wager lockout from K-tox -- chlorosis up top and some yellow, blotchy leaves at bottom -- may see hints of other deficiencies due to lockout too. Double check pH first before fiddling with nutes, but you need to cut that "warm/cool" EC by 1/2. Add twice as much water as it says to equal parts. That is an insanely high EC unless there;s some weird gimmick going on with this product and soil.
Either way.. too much..

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Nitrogen Toxicity?Not sure if this is nitrogen toxicity or normal leaf color. Crinkling was caused by too much light and the fan. Got better in 24h after adjusting grow light and fan. Plants are starting week 2 of veg, Hulkberry Auto. Medium is light mix soil.

WHY?? Still looks like Calcium Deficiency?? HELP!!!Can Someone Please tell me what is going on here? I have a detailed diary if you have any thoughts on why it still looks like a Calcium Deficiency.

What deficiency is this ?What is happening to my plant right now ?
I believe it is calcium deficiency also could be Manganese from the pictures. I did not add CalMag during the first weeks.
Usually Calcium deficiency shows after 4 weeks and during flower but not likely in soil.

Runoffs are significantly below inputs-Do I have a problem?Runoff continues to be a mystery. When watering I continue to get significantly less Ph and PPM (4.8 ph and 109 ppm) than my inputs (6.2 ph and 155 ppm) but the plant looks healthy. I have no idea what is going on or if its even a problem. Should I be worried and what can I do?

Autos reacting to All-Mix: Slight nitrogen overload?Pheno one showed very "leathery", weak, hanging leaves of dark green. Same time the fungus gnats had a run and the population doubled. After second LST also the stronger plant showed those signs on the younger upper leaves. Also curled down a little. Slight nitrogen toxicity?

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

PH-Problems in SoilBefore repotting, the pH value in the soil has always fallen to below 5.5. The plants always have an iron deficiency. I then repotted the plants and that worked well for 14 days. Now they are showing PH deficits again. The soil has PH 5,4 -4,8. What could be the reason?
