Nutrient lock out hot soil question - stunting starts on 3rd set of leaves always?

Overgrothostarted grow question 5y ago

I noticed that they always deteriorate when the third set of leaves are forming. If these are in fact stunted from the nutrient lock out due to hot soil, does it make sense that growth is vigorous until the 3rd set of leaves form?

Its burn, not lockout. Rather, its locked out due to an early burn, if the soil was indeed hot. Re-pot em in proper ph and low nute medium. They will erupt once cured

Cutting fan leaves Just cut my fan leaves 😳 the stems we’re turning people, if I’m not mistaken it’s an early sign of an old leave that’s not as efficient in the photosynthesis? and it was covering the new growth, Or should I have waited?

Deficiency ? Chlorine from tape water ?Spots appeared after last watering, 4 days ago. It doesn't seems to evolve to more spots. Using basic gardening soil. Chlorine in tape water X 4 those days, because of covid-19. So if not a deficiency, might be Chlorine ? Or Chlorine killing life on the soil? Suggestions ? Help!

Noticing slight brown spotting on a couple leaves accompanied by the tiniest little bit of yellowing/tip burn on the very tip edge, any advice?Noticed today prior to feeding that i’ve started to get some slightly brown spots on 2-3 fan leaves and also noticed lots of tips starting to show the tiniest amount of burn on the tips. Dropped nutrients to about 80% dose and added some calmag. Any advice would be great.

Never really noticed this before, but it's also been a long time since I've grown inside. The tips of each jagged leaf edge is pointing up. Just curious about it.

In addition to former question I am growing on Cocos mix. I add Calmag 1 ml/L once a week. I do not measure PH (never did) because of organic nutrients. no runoff, I like to keep my plants a bit dry (about 150 mBar on Tensio) for better rooting. So just more Sugar Royal? Daily 1ml/L instead of 2ml/L weekly?

Can anyone help sort out the issue I'm seeing on the lower leaves? I think I'm either between nutrient burn or potassium deficiency? I did up the nutrients a bit this week when I saw yellowing, but also have had high runoff pH the whole grow. Though haven't seen any other issues.
