Heat/light stress are now under control after raising both lights up significantly and also putting a supplemental cooling unit in the grow room. These girls will have just less than three full weeks of veg before the light goes 12/12. These plants are some of the most resilient that I've grown and im excited to see the end result.
I dig what you got going on but there looks to be a couple issues in my opinion. Lotta conoeing of the leaves and some interveinal chlorosis. You got calcium issues most likely caused by soil ph being off. Most likely too acidic. Im not sure about the chlorosis but you can bet its not good. Get your soil ph in check. Easy on those GH nutes. They're super strong and can turn your soil acidic over time. Good luck dude
Belle amico complimenti... Se puoi alza leggermente l umidità fino al 60-70% in questa fase.. Così possono traspirare bene dagli stomi e avere una buona fotosintesi
