Thank you! I did stop using my cal mag in my watering because Dr Earth's had fish bone in it for calcium. But that didn't account for the Mg in it too. I'll start including that with my water and hope it helps clear it up. Do you think I should wait for this to clear up before flipping to flower?I've had this while adjusting to the switch to LEDs. It seems to be an Mg deficiency. The plant draws magnesium from the lower leaves and they become more sensitive to light. Note that the parts of the lower leave shaded by upper leaves are not burned or are less burned.
So I would say more Mg.
Thanks for the advice! Super helpful.It's usually a good idea to make sure they're healthy. Those leaves, of course, will not heal themselves. They'll always be burnt.
There seems to be an extra demand for magnesium under LEDs. You pretty much have to make sure they have plenty, until at least halfway through flower. My present grow is the first under LEDs where I didn't fry the fuck out of them.
Nice looking plant structure! How old was this plant at the time of photo? Also, for scale, how big is your soft pot? Finally, did you get the problem under control?Thanks for the advice! Super helpful.
Thanks! The plant was around 55 days at the time of those photos. The soft pot is a 5 gallon. She's been a slower grower, I believe partly do to lower temps in my basement which I've gotten better control of. I flipped her to flower 3 days ago. She's really recovered in the past week and a half or so. I started dosing cal mag in each water cycle, started using olympus up (ph up) to raise the ph of the soil (I did this twice and am planning on doing a half dose every 3rd watering) and lastly raised the light to let the leaves cool off from the burning from the problems. Sounds like a lot but i did a lot of 1/4 and 1/2 doses when trying to fix the problems. Some of the bottom fan leaves are still hurting, but all of the newer growth above seems to be doing great. I'm going to wait until day 21 into flower before pruning anymore. Let me know what you think. Left pic is today Day 91, right pick is the day I flipped her Day 88.Nice looking plant structure!

It really looks great to me! I just started mainlining my Shiskaberry—made the first top cut yesterday, so I’m particularly interested in yours.Thanks!

This makes sense. I think the addition of cal mag in to my waterings helped a lot, on top of getting soil PH higher (it was showing a ph of 4 right after I watered even though water going in was 6.6). Will definitely be paying closer attention to my cal mag dosing in the future.If you have coco in your medium, it eats mag so you need to supplement.
Awesome. Mainlining is fun. Sculpting a perfectly symmetric plant is extremely satisfying. Hoping the bigger buds with 8 main colas comes true. A little risky doing such HST on my first plant, but it's expediting my learning quite a bit. I'll keep you updated and would love to see how your mainline journey goes, as well.It really looks great to me!

Mainlining is as much a science as it is an art. Your looking great so far and I think your defoliation looks fine man let it stretch more and see where your at, I try not to do too much defoliation after 2-3 weeks into flower.Just a quick update on the mainline, she is doing really well! I've selectively defoliated her a little bit here and there to get rid of some larf and long stemmed fan leaves that are blocking bud sights. How do you guys think she looks? I'm scared I'm defoliating too much. It's day 14 of flower and I'm going to do the deep defoliation at day 21 of flower. I'm hoping she stretches a few more inches to increase nodes for the bud to grow.
Let me know if anyone spots anything off, if any of those lower branches look like I could remove them or if it looks like I may have defoliated too much!
Does anyone know WHY this is?There seems to be an extra demand for magnesium under LEDs.
Are you saying the led has more intensity than a HPS? Or just a more powerful LEDIn many cases, I have seen a grower switch from HPS to LED and the intensity of light is higher. This leads to light burn that is often mistaken for cal-mag
Probably Liebig's Law of the Minimum at play. Light was a limiting factor in growth under HIDs. With more light, the limiting factors became nutrients.Does anyone know WHY this is?
