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

Yellow tips on most leaves. 1 gallon yesterday, no nutes (every other water) at a ph of 6.5. just did her stretch. Otherwise, looks good and healthy. Lifted the lights up just in case, but I want to stay ahead of this. Any thoughts or recommendations?

Second grow, second leaf issues. A quick google leads me to believe its phosphorous deficiency, that may be being made worse as its getting colder? Is it terminal or will she survive?

Spots on plant? Is she sick and how can I help her?She has some spots and I'm worried for her. This plant is the only one in my tent like this, none of my others have spots. And I did transplant her to a 1 gallon pot, but she needed it. Her roots were growing out of the solo cup. Does anyone have any ideas what's wrong with her?
