It might possibly be wanting more ferts. Noticed some yellowing leaves down below. I know that's common in flower, but you've got at least another month to go. Get a second opinion before you go and add more fertilizer though.
Lol. If it wasn't for that one pic we'd probably never know if it was soil or hydroWhats yer ppm
Ph, rh, temps
Whoops nvermind im not a dirt guy
Thanks for your help and tips, appreciate it very much. By the way, the strain is Girl scout cookies from MSNL, water the plant 2-3 times per week, every 3rd water i give it 11-35-11 NPK fertilizer, ph of water is around 6 and runoff is slightly higher but no more than 7. Temperatures are around 25-30 when lights are on, and 20-25 when off. Where i live it's not easy to find bloom solutions so i have to use more industrial strength stuff, but i've seen other growers using the same stuff with great results. Thanks again for your helpLooks good to me. I think it probably is the light is a little too close. It just seems to be way too uniform (indicative of something like light bleaching) to be something going on with the plant / medium chemistry. That wouldn't be so uniform across the plant like that. I haven't used an LED before but I have read countless times how their intensity can do exactly this. I don't think it's necessary this time around, (unless you want to or someone asks you) but next time you need to include a lot more details like what you're growing in, light distance, fertilizer strength and schedule, watering schedule, pH, temps, really anything you can think of that could influence your plant in any way in your first post. If ya don't, a lot of people won't even bother responding
Beautiful flowers, nice grow. How long did you veg for?
Actually no i haven't upped my feeding, I fed the same amount for the whole flowering period, next watering i will add some more nutes and see if that helps, thanks
If I remember correctly, nitrogen is a mobile nutrient, which means any deficiency would show in the older leaves first as the plant leeches it away to provide for the rest of the plant. I think it's possible that while trying to diagnose an issue related to light bleaching, it was discovered that his plant could probably use more fertilizer. The top of the plant is lighter than normal, the middle seems fine, and the very bottom is showing nutrient decencies. OP, I would fertilize feed half strength first water, then straight water, then regular feed for your 3rd water. Or you can do it another way, main idea is to introduce more ferts slowly and see how your plant responds.
Outside of the 11-35-11 do you give it CalMag or something similar as well? What is the brand of fertilizer you use? It's possible what you're seeing is some kind of micronutrient deficiency. Do you have better pics? The plant looks like a nice dark green from the side and the top view looks completely different.
Yeah, most of the time that is the case. It's important to rule out though, because too much light can result in burning through nutrients as the plant is uptaking more to account for the added light and basically, it can have nutrient deficiency and nutrient burn at the same time, and it just throws everything out of whack. He never did mention the light distance. It's easy to have an LED too close because they aren't as hot and it tricks people up into putting them closer than they should be
I wouldn't be to worried about adding to much N at this stage but Mag, P and K. They really like a good Hit of P/K midway thru.
Sorry i can't post a link because of requirements, if you google "solinure gt9" is the fertilizer i use, as i know it already contains moderate amounts of micronutrients. I don't add any calcium, i don't think it looks like calcium def. One more thing tho, i've noticed that pistils in the middle buds are slightly brown, but on the outer parts they're all white and healthy, LED is now at 17'' above the canopy
CalMag also contains magnesium and sulphur. I agree with Luke, fertilize more. However, you want to make sure you arent giving too much light or your problems will only continue. Do you have a smart phone? Download a Lux Meter app for free and it can give you a general idea of light intensity. If I remember correctly, 40,000 lux is optimum. The discoloration literally looks like a hotspot which is why I think that's at least part of your problem.
I'll check lux when the lights are on later today. Do you mean hotspot as in heat could be burning it? Because it doesn't even feel warm when i put hand over a canopy, but i know that's not accurate measurement for leds. If that is the case could a fan circulating air above and on the canopy, as well as raising lights resolve the issue?
and see if any of that makes sense to you. Google cannbis zinc deficiency and look at the images, looks kind of similar. I do see slight interveinal chlorosis on the top down pic. All in all though, just keep an eye on her. She looks pretty damn good. She probably looks better in person, too. Feed her a little more, and go from there. Good luck
No I meant as in bleaching. Here is specs for your light:
