Fan leaves dropping

Just a quick update, I have added a light and reduced the amount of wind my plant was getting. I think one of the fresh air intakes was bringing in cold air right across the plant which caused the leaves to curl badly. Possibly due to too rich of nitrogen in bud too. Fortunately the leaves seem to be doing better. Not perfect yet but much happier looking. Thanks everyone for your input.

That light sure is close to the plant!

The picture is a bit deceiving, I pulled the branch down to take a picture. The top bud is actually under a completely different light behind the one in the picture that is higher up. There still closer than I like but the bastards stretched like crazy. I was not prepared. Live and learn... first rdwc grow.

Could you pull it down somehow if its a issue? Not ideal but I've seen others do it in a jam.

Yes I can if need be but so far I have about 8" from the light which isn't to great but it is what it is. These plants are just over 5ft tall and bushy.
How many watts are those lights, that is one of the high bay styles like they use in greenhouses isn't?

I've got x2 PH2000 2000watt linear phlizon lights, x2 600 watt lights and x1 900w Mars hydro in a space that is about 11ft long, 3 ft wide and 8ft tall.
What the lights actual wattage output, any idea? If you haven't invested in a watt meter I would do it. My next purchase will be a light meter and temp gun for measuring leaf temps.

Ambient Temperatures
Ambient temperature is the temperature your growing space sits at. It's affected by external factors like the temperature outside, as well as internal factors like the heat (or lack of) coming from your grow light.

Temperatures inside of your garden play a big role in how well your plants breathe and absorb nutrients. The ambient temperature of your grow room plays a huge factor into the humidity level in it, which will affect how much your plants will sweat, absorb nutrients, and ultimately grow. Excessive heat will make your plants breathe and lose water quickly, while excessively low temperatures will slow down the absorption of nutrients, stunt growth, and can lead to moisture build-up (and all the problems that come with it). Photosynthesis in plants can only be achieved at certain temperatures, so even if the humidity of your growing space allows your plants to breathe properly, a bad temperature may not allow for your plants to convert nutrients into usable energy for your plant to grow. Your plants are constantly trying to grow, and when temperatures are off it makes it difficult for the plant to do so. No matter if your plants like it tropical or cool and dry, knowing the ambient temperature of your growing space is important in making sure your plants are getting what they need to convert nutrients into usable food. That includes making sure the temp in your room isn't affecting the temperature of your water or medium temperatures. Common grow room temperatures include (but are not limited to):
  • Clones/Seedlings: 72-82°F
  • Vegging Stage: 68-78°F
  • Flowering Stage: 68-77°F
  • Temperature Drop: 10-15°

I haven't invested in a lights meter yet. But will look into that for sure, thanks for the info. I do want to upgrade my lights one of these days.

My temps sit at 70F lights off 78F lights on. RH sitting at 50 at the moment. Will drop that down when the buds get bigger.

Found that with google. It doesn't say whether that is ideal for plants grown under HPS/MH or led. So much to get right when growing, so many gadgets that are supposed to help us do it but like I said my best plant was in the living room, grown in the winter no less. :wall:
