Leaf edges pointing up, why is this tho? Rh: 65% t...

Your plants looks like to have some issue that are hard to have with your values ( RH and temps ) , it is the temps of the box or the temps taken at the same level than your plants ? is it really 70% humidity here ? are your sure about the ph value of your mix (my mix with green buzz are slightly too acidic so I often have to correct my ph) ? So it's looks like a low rh or (&?) heat issue ( edges curling up )

Heat stress or over watering maybe both if autos give a spartan feeding regimen custom the strains liking start at .125 strength graduate up to 50 percent strength make sure leaves don’t go above 81 degrees for stress use laser temp gun

Hi buddy... according to what i saw on ur previous weeks you had some problems.... over watering among others autos are really sensible....most than photos ...how is your soil mix made ?? it could be too rich.....to avoid freezing ur seedling it is recommended to cut your soil with neutral as coco perlite etc...it s ensure a better penetration of roots....and better roots biggest plant in veg mode autos doesn t need a lot of nutes, roots additive (or others additive) is ok.... environnent condition are also important but i don t think 65% of humidity is a real problem at this step... if u respect the good cycle wet/dry for ur soil... a major part come from... in my opinion for next time try to do a foot print in ur poot that u fill with really light and aerated mix.... like that growdiaries.com/diaries/33542-purple-haze-the-7-chakra/week/159076 feel free to take a look cause i give a recipe to avoid this kind of problem....with this 3 layers tech u will see a big improvment of ur future grow👊 hope this help....happy growing

hi friend, I am a newbie. I don't know if this could be the problem but surely the humidity is too high for that temperature. I advise you to raise the temperature by 2°C or lower the humidity at 55%.
