Hey k , yea the lights , i ask everyone who posts a pic to present it in a clean white daylight or clip on flouro bulb , not so much in your case because im so familiar that i can already read the plants ,,,, but
Yellowing can come on out ov no where , and your pic confuses me sometime , if i dont see them for a few days , so try a reg white light bulb or camera flash if you can,,,,
The look fine anyway , cal / mag is easy to overdose causing more leaf problems .... so easy is best anyway...
Some plants are finicky like your sd hybrid , any way the wind blows , one stretch perfect , next day purple or yellowing , 3 days late back to perfect again.. deff do not even wory about fixing anything now , they are really growing well and doing what i like best , just running the race to the end nice and steady , its when one slows down or gets defeciencies and needs to recover once flipped thats where you can get a little messed up ....
You just want to pull the starting gun trigger and watch them go to finish without any pause....
As far as transplant , im superstisious , i like the roots to grow a week into their new home , get other opinions on that , maybe totally different in coco
My reasoning is that the plant focuses on different tasks at different times , using different nutrients to accomplish the task , leaf , root , nitrogen , stem , flowering utilizes phosphorus ...and the energy now goes into bud making , not so much root developement, so i like to make the feet nice and comfy before i flip,
But no harm , will work either way.......
You always say things like " they arent happy today " or didnt like what i did to them today - so if i had to predict your life saving instincts , youll prob be like me and let them settle in bed before physical therapy starts
But everybody does it there way and you have to learn for yourself like everything else.....
