i just built a greenhouse for my plants and im having a problem

i kept getting mold on my plants from all the rain in colombia, so i built a small green house. the plants looked awesome when i put them in the green house a few days ago. now one of the plants if having issues, i haven't changed anything nute wise. it was getting pretty hot in the greenhouse so i cut so holes in it last night to let air in an out to reduce the temps.here are pics of the leaves anyone know what might be causing the discoloration? thx in advance for any info, rm

has your soil been able to completely dry out or has it stayed wet the whole time?

the soil has never gotten really dry, i water them every three days, i stick my finger down 3 or 4 inches into the soil to see how damp it is. it was a lot hotter in the green house, than when the plants were outside. after putting them in there the soil did get dry much faster due to the heat. i have condensation on the inside of the roof of the green house right now. i will see what the temp is inside next sunny day, it is a little overcast today. thx for taking the time to help, rm

basically when the plant gets to hot its unable to uptake the nutrients which is causing lockout, plus you wanna make sure you let your soil completely dry out between waterings because if you don't the plant will "suffacate" and will not be able to "breathe" due to roots staying too wet too long

the temps are 81 inside 73 outside 72 humidity, it was probably nid 90's inside the last two days, it never ever gets 90 here in medellin, do you think the 15 degree temp diff for two days shocked them? one plant is fine the other changed the big fan leaves color quickly....
