Light too close?

[ponzi314]

I think i know the answer but just want to make sure. My light is too strong right? causing it to wilt a little?
Current light is Spider Farm SF1000, Running at 100% at 19 inches away from top. I just backed it off to 60%. I had it at 100% because i keep struggling with stretching so thought she needed more and i read on a form someone keeps at 100% from seedling on.


I get so many mixed messages on correct height/intensity to use it hard to keep up. Im assuming i didnt mess up the plant and it will recover but probably didnt help her.

Sorry but you have embarked on a life of trial and error, elation and depression. 100% for seedlings is too strong. Lower your light about six inches and cut it to 60% power. You're going to have to play with power and light elevation in order to find out what works for your set up. On a different note, I believe your plant is showing signs of a PH imbalance.

Most soil is not what I call soil.

Drop your pH to under 7 with a few drops of lemon juice and see if you get improvement. 6.5pH may be tour target but depends. Good soil is forgiving. Bad soil is just bad

I’m hoping it’s good, i got it at a local nursery.

Can i put the lemon in the water dish on bottom or right ontop

I'd pH your water to 7 to start and pour it through from the top...until you get runoff. Too much runoff in soil strips the nutes out of it and the soil takes sometime to recover.

I used the Photone app to position my younger plant to receive the proper intensity and duration. I just had to move it out of the direct footprint until I got the correct parameters and everyone is happy.

tried checking this out but too cheap to purchase it for LED when i dont really know if it will gain me anything

[ponzi314]

Id say she recovered nicely

[SoOrbudgal]

Yep she looks good for sure. I like that stretch going on. The more familiar you get with that light you'll know the sweet spot that the plants respond best to.

[ponzi314]

I just raised a power a little more (80% to 90%) because of the stretching. My tent is only 6 ft so i dont want to run out of space

[OldManGrower]

Yeah, available headroom is a major issue for me as well. If I ever purchase a new tent (which is doubtful) I would definitely go taller. I only buy seeds expected to grow to no more than120cm, I then top and LST to help keep them short. Right now I have seven plants, the tallest is 71CM..

[ponzi314]

Yea its tough, 2 more feet taller would be great but i just cant do it. Since posting the above, plant shot up. Almost at light already
