First grow light bleaching?

[Curiosity|]

First time growing environment is pretty stable temp averages 75-80 and rh averages 50-60 I’m in week 2 of flower I’m using a es180 v3 in a 2x3 the lights are at max and the new bud growth kind of looks yellow so I’m concerned also it looks like I’m having some deficiency’s and nute burn at the same time lol I’m not sure if it’s from light intensity or if it is a deficiency maybe both I can’t raise my lights any higher the closer sites sit 14” away from the light and the furthest sit 23” away I can turn them down but then I’m concerned the ppfd won’t be high enough for the lower sites

It does look a bit like a light issue, I see some rolled leaves tips and ruffled leaf margins. Try turning the light down to 80% and see what happens. That said, new growth is often lighter in color, wait a couple days and see if they darken up.

Why the double post?

If it's the Electric Sky 180 V3, your light is generating a lot of photons in the center of the light but light levels fall off very rapidly so you need to get the plants out of the hot spot.

The PPFD map is from the product listing on Amazon.

I do see a lot of leaves that are "praying". That's considered a sign that the plants are getting a lot of light but I suspect the it indicates that they're on the cusp of getting too much light. In the case of the leaves at the top of the canopy, they're at an extreme angle so it is probably best to back off a bit.

The leaves at the top of the canopy have a saw tooth appearance. I don't suspect that's a light issue because leaves toward the bottom of the plants have a similar shape. If that's actually the case, I suspect it's genetic because leaves that are 12"± different, vertically, are getting very different amounts of light.

Spending $32 for a Uni-T lux meter is money well spent. You've got a light that has an uneven PPFD map so the meter will help you position your plants to try to get them in a position where the light cast is more even.

The PPFD map below is for a 12" hang height. As hang height increases, a PPFD map tends to even out. If you get the lux meter, it will be easier to adjust hang height and dimmer setting.

I don't know that the light color of the leaves is result of function of "light bleaching". My experience has been that plants will taco//canoe to reduce the area of the leaf that exposed to light and/or they will rotate the leaf vertically around the petiole. I know of bleached flower buds but that's requires a very specific set of conditions to occur.

Re. the light color of the leaves - what's your nute regimen? My understanding is that light colored leaves can be a sign of not enough nutes.

Per @Phytoplankton , I'd drop the dimmer setting, and then send Amazon some of your hard earned money and get a light meter so that we're not…shooting in the dark here (pun intended).
