All four plants were topped for the first time and then staked down with landscape fabric staples. The mutant of course was topped twice due to having two mains on one plant. Impressive growth rate so far and will most likely defoliate at some point this week.
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
