Light time

She looks fine, but stop spraying the leaves. There are only a few instances where foliar feeding is required. If your RH is ridiculously low or if you need to correct a major deficiency fast are really the only reasons to get the plant itself wet. She does look like she's developing nicely though. She's not stretching and she doesnt look stunted which leads me to believe your light is sufficient for the time being.

Reference a DLI chart... with accurate specs form light you can ballpark how much light you can give over X hours... Same DLI will roughly result in same yield.... with some common sense applied to rational comparisons. umol/s x hours of use x some 'factor' i won't go into without a textbook = DLI A DLI chart exists in my growdiary.com profile's comment section - it is hosted on gd.com, so no offsite web pages. Google images can easily provide one too. Without CO2 you want to start around 40-45DLI and observe plant. If it droops or otherwise wilts, especially last hour or few before lights out, it is probably receiving too much light, otherwise it can handle more.... when it droops too often and for no other apparent reason, you know to back off and that's likely as much as it can handle in your ambient environment. If your light doesn't reach ~40-45DLI over 18-24 hours, you can run it as long as you want, but some dark period is likely beneficial even so. Unless you control temp and humidity to conform to a VPD chart in a precise way and/or add CO2, this won't change much.

Hi, The seedling is looking good, For autos you can start the light at 12/12 and don't change it Unless u have photoperidic phenos, then keep the light 18/6. Remember, no mater what time schedule you are using, the autos will bloom when they programmed to. Try to keep The light around 20”-24” away from the seedling or as recommended by lamp producer. Happy grow !!!!

Hey she is looking good so far. I normally start with 18/6 until about week 2/3 and then 20/4 for autos. Hope that helps and happy growing
