The whole plant is yellowing

Not sure how you checked you medium ph, but I’d double check and compare with you good plants.

also from your soil. “When using Royal Mix, you can expect a period of 3-6 weeks after each transplant before using liquid fertilizers, depending on the volume of the pot used (the bigger the pot, the more nutrients will be available for the plants).”

so it may need fed now.

A lot of purpling stems, always happened to me from ph lockout.

if needs food, I’d give something near 2-1-2 or whatever you normally use that works for you.

Not sure Epsom salts is good for much from my research

Epsom salt mixed into tapwater is what you pay money for, cal mag! Better research some more.

Someone made suggestion to op that his plants may have different nutritional needs/requirements, I don't agree and was just asking for evidence of it.

Something scientific would be great. I'm over trying to find anything meaning full on the topic in this thread though

Have you tried YouTube yet? You haven't posted a scientific fact yet. Just anecdotal evidence.

Didn’t read all the debates but even before you posted pics I was thinking… cold spot? She’s getting cold is my guess.
If it were me I’d try diverting the airflow on the intake so it doesn’t hit the plant direct. Piece of cardboard for the win.
My tent sits on cold concrete so I leave a heat mat at the bottom set to 70 degrees. It keeps that floor and their ‘feet’ from getting cold at night even tho they don’t sit directly on it. Way cheaper than my old heater to run too.

Bottom heating definitely works but you have to be cautious about medium drying.

Your leds will last longer but your plants will not like these temps and it will effect your crop size, you have all the gear but no idea.
this may help you learn some facts, so you can help others.

I will certainly not be an expert but in any case I have always grown with these temperatures obtaining an average of 100gr per plant and I think it is a good result. I'll tell you .. I only had problems with temperatures higher than 27 °. I am not worrying that much about the temperature as I think it is acceptable20201209_134931.jpg
