Light Stress or Deficiency?

Agreed zypheruk, the lighting was the issue all along. I've since raised to 150W (about 500umoles) and lowered to about 20".


Skoal- definitely not a watering issue, unless possibly underwatering.

Glad your sorted, enjoy you growing now.

Glad you sorted it out. Didn’t think light stress would present itself like that.

I’ve never had light stress issues but I use MH bulbs.

Yet his original post says light 12" above. Last post he has "lowered to 20"". Read up a bit on LED and plant issues including calcium deficiency from using them improperly.

When my 135 quantum board is ordered I certainly will.

Thanks zypheruk.
Here's a pic at 400umoles, yesterday...

Unfortunately today was a different story. 500umoles was a bit much so I raised the fixture back to 24" and am at 400umoles canopy. Still at 150W, so four inches makes a big difference.

I hardly want to upload this picture from today- mostly because I know what's going on now.

It was also watering day, so some of the appearance can be attributed to that (but not much). I also fed nutrients for the first time, a 1/4 dose FoxFarms Big Bloom 0-.5-.7 soaked the pot until runoff not quite 10%. Let's see what tomorrow brings.

Pic is after feeding, yes the soil is supposed to look wet right now. I'm not overwatering.

Yeah I recently had my new clones claw like this after having my lights too closely, I use an ES300 that is 3 1/2 feet from canopy at 100% and they are loving it. Good thing about the light stress is that they recover very quickly as long as they weren't burnt. Keep them at 24inches and let the plant grow into the light, you'll know your light is too far if you start getting stretching in veg but honestly doubt that'll happen. Patience.

Hi .RootDown,

What does your watering schedule look like? How many days in the week is it getting water?

Typically a plant doesn't droop after a watering, instead they perk up a little. Especially if they needed it.

I realize you have plenty of perlite, but you "should" be judging when to water by the pot's weight. You'd be surprised how much water can still be in the pot, even if the first inch or two on top is dry.
It's a decent sized pot for the plant's size too. There'd still be a pretty decent amount of it without roots, it may have wet feet.

Underwatered and overwatered plants can look exactly the same sometimes.

Good they improved a little when you raised the light. But it could still be a watering issue, especially the drooping after being watered.
If the plant is trying to photosynthesize, but rootzone is too wet it'll droop. The same can't really be said for too much light, unless the droop is happening towards the end of the day, but perky at lights on.

Anyway best of luck, and hope whatever it is sorts itself out.
