Suff's Pineapple Express

I am super, Not Happy, about (what I’m assuming is), Light Bleaching.

 I’ve checked back a few times, here & on our Instagram account & no one has weighed in to confirm or offer direction, so I continue to research. Also, having just been pushed back into Lock-Down, the option of connecting with anyone outside of the house is pretty much squashed. 

 Everything I’ve read points to Light-Bleaching. In every post I’ve seen, “Nute. Burn” has fairly distinct “burning” & crispy edges around the leaves. What we’ve experienced is two young plants that have found themselves growing ever closer to a fairly bright & intense light source, with little to zero “burning” or crispy edges to the leaves, until today.

 On their last water, (Dec. 23rd/2020), they both got a smaller drink & I also re-arranged the lighting set-up they share with the clones in the Lab-Tent. We’ve had two lights running in the lab tent. The 1st is a 300W LED Bank we got w/ our initial kit & the 2nd is a 1K W Bank we added later. The 300 is up top, over the clones & the 1K is in the bottom, (these girls were Veg.’ing in the bottom). My working theory has been that they may be getting too much light via the 1K plus added drench from the 300W. Add to this, that they are growing, ever closer to the LED Bank & the “Bleaching” Idea just pans out, (at least, for me). On their last drink, I re-arranged the lighting. I moved the 300W down to the bottom & the 1K up, over the clones. You can clearly see the results. We made zero improvements. 

They were pretty dry today, as was the surface soil for the clones, so everyone got a big drink & a big spritz. I noted 2 two crispy leaf tips on PE#2 & she’s been the bigger of the two girls. I’m chocking this-up to the girls going pretty dry between waters. Today, we took the shelving out of the Lab-Tent entirely. After getting their drinks & trimming-up some leaf tips on the clones, everyone went back into the tent, zero shelving. There is now 43.5” from the top of the plants to the LED Bank. We’ll see where we land next week.
