Seedsman grow under lumatek Zeus 2.9 600

Looking good today light turned to 1000w and 600w will be buying led lights tomorrow finally Gave good feed today and they’re loving it worse especially under the 1000w looking forward to seeing a lot of stretching here Very vigorous growth already a lot of plants showing they’re sex no males thank god hoping to fill my space which is 3.2m x 2m total of 6+ sq M2 the plan is to order 2 lumatek Zeus 600w pros as I can’t bring myself to buy Mars hydro viparspectra or spider farmer friends all use lumatek and swear by them so I’ll join the lumatek club added 100 plant bends and got half way threw will do the other half tomorrow and get them all spread out well One lumatek Zeus pro 600w 2.9 added plants are living the dream now So now I’m laying a lot of attention to my room conditions I am considering a c02 system here as my room is already sealed but I’m also paying alot of attention to my VPD and after 30 hours of tinkering I’ve finally got it into the sweet spot at 0.83 which is perfect for early flower going to pay alot of attention to this and hopefully keep it in range without any controllers or expensive equipment which would probably be less hassle but sure , I’ve it dialled in I think lights on anyway lights off I’m still tinkering with don’t want to go near my girls lights off for fear of stress and hermits even with a green light so for now I’m gonna update my thermometers and hydrometers and buy a humidifier controller 30 quid Amazon or something and keep my humidity where I want it fans are right down to lowest setting and still good airflow temps are at 25oc and humidity 55to 60 percent so really growing well noticing some tiny white powdery spots very concerned about this any feedback would be well appreciated thanks guys
