Deficiency going on?
Slightly yeah, I was a bit too light on nutes after repotting and got some N deficiency. Added nutes to the water today though so should be better in a few days. Some of the lightness on the upper leaves is actually bleaching though from accidentally letting it grow to touching the light when I didn't check it all last weekend.

Other than the nute issue what are your thoughts on it man? Which LED lights have you used before?

Plant looks good so far. Flowering is starting to progress nicely, a good number of bud sites have started to develop. Won't have another update till a week or two from now. I'll get pics up next update to show how far along she is.

hope you've been able to clear up the deficiency. Other than that they look good. I like that you supercropped them, my yield increased when I started to do this. I almost feel like that is the best way to grow under led because you can get the whole nug horizontally under the led for max exposure. What kind of soil/mix are you using? What is your feeding regiment like, ie, nutrients, supplements, additives, frequency and amount?

I've only used leds from advanced. the 180w extreme flower and the 200w diamond series and i really like how they've performed for me.

So had surgery the other week I haven't felt well enough to even water until today and hadn't thought of it beforehand so she went almost two full weeks without water. She really looks rough now, I also found out that letting the plant grow into the light actually does burn the plant pretty bad. Didn't really see any bleaching but a few of the leaves are really crisped from rowing up to the edges and touching the light. Because of the design of the light this means they were effectively sitting against the heat sink and the result was pretty bad. I'll get pics up early next week, didn't feel up to after trying to fix things today. I ran a good bit of water through to thoroughly soak the soil and get rid of any salt buildups. I'll feed again next watering long as she's starting to look better by then. Otherwise I may just scrap her for hash and start over.

I'm just using a mix of peatmoss and perlite. The veg nutrient I use is vigoro grow, for flower nutrients I add miracle grow bloom booster and cut back on the vigoro but not entirely bc the mg lacks enough of the micro nutes. I find that with the LED I only need to water every 3-4 days and I feed every third watering unless it looks like there's a deficiency and I'll add another feeding in after one watering. I don't use any additives/supplements, haven't gotten a good cal/mag yet either but I need to soon. I started w/ 1/3 strength nutes about week two of veg and moved up by 1/3 each feeding till at full strength then for flower switched from all veg to 2/3 veg and 1/3 flower, now at 1/3 veg and 2/3 flower, then I'll go to all flower for the last two weeks ending with 2 flushes before harvest.

I used this feeding schedule for one of the ones in my last grow and it ended up yielding nearly 2g more than the other one which got just veg nutes in veg and flower nutes in flower. Considering that between the two little clones I only got 11g total, that 2g advantage to the one was a pretty big margin for how small they were. I'm debating whether to try doing 6 small clones in 6" pots each topped at third node and then vegged to 8" tall to flower. The clones last time were flowered at about 8" w/o topping and ended at just under 12" tall so I think I could get a pretty decent yield out of them doing that.

As far as how the HSS compares to other LEDs, I'd say that it is probably best reserved for either a very small full cycle or just a mother/clone veg light. The GLH light I have is definitely much better for growing anything taller than 18" and has a much better footprint. Any advice or criticism you can offer are greatly appreciated.

Haven't been on in a while so never bothered to update but I ended up chopping her on the 10th because she wasn't looking any better and just continuing to deteriorate. Ended up getting a bit over a half zip of smokable bud and bout a quarter of underdeveloped bud that I threw in the cooking pile. So for being cut at 5 1/2 weeks I don't think I was doing too badly, other than the obvious failure which led to her demise. If she'd gone the full 10 weeks I think it may have yielded an ounce or so, not horrible considering I was planning to have two plants her size in there. Next grow won't be for a while as I'm planning to move next summer and don't want to hassle with it until then, pretty much just need a break for a bit.
