hi all, love the forum. got lots of helpful hints but this is my first time posting. right now, i have a pc grow going with an autoflower white russian from sagamartha. things started off okay but now, after about 2 weeks, leaves are starting to have brown spots. initially thought i was underwatering...(about 250mL of water every 2-3 days, no nutes just drinking water) as I have the plants in relatively small pots and the drainage is pretty good. Before i water each time, i also dig through about two inches down and seems pretty dry. just watered again today...last time was three days ago and leaves are starting to droop after just an hour. another complication...theres a lot of remodeling going on in my building right now so it gets pretty damn dusty here. also, the plant is tipping over and not growing straight.
In my PC box right now I have two 24 watt CFL day lights. Was going to pump it up to three 24 watt CLF soft lights next week once flowering begins. I have it running on 20.5 hours on/3.5 hours off. Have fans installed but don't have them running cuz its quite cold in my apartment and the temp inside should be about 70-75 degrees fahrenheit inside the box without it. i leave the door open a crack for ventilation.
im going out of town for about six days. told my friend to come by and water the plant in a few days however if im overwatering, then should i just let them be until get back? pictures attached....PLEASE HELP!
