First Grow, looking for insight on fan leaf issue!

You know, I was wondering if the new growth was feeling overwhelmed with light and can't handle it till it's older and why the color shift is so drastic.

Then the large leaves look good for awhile, but as they grow with age they then start getting burnt tips from the Coco Loco.

The original reason for four lights is I planned for four plants, but it didn't quite line up right and I ended up with just the one for now.

I knew the performance wasn't as great on these boards as some others, so I figured I'd get away with banking the lights at an angle and spaced out in a square, with about a 2" gap between each border of each board, then the plant sits square in the middle of them. If you had a birds eye view, you'd see the plant right down the middle center gap.

I'll take the advice though, but I'm gonna cut back only 2 lights for the sake of keeping my tent as organized with cords and positioning as it is. I'm gonna leave the lights where they are at though. Last time I measured it was like 34" from the top canopy.

I've read that LED boards are still kind of a mystery when it comes to light distance and where the plants like it the most.

I have 3 plants a little smaller than yours under one of those lights. That will change down the road of course, but at 100% and 20in, they are doing well. You're definitely set up for the future though. :bigjoint:

It’s not really, just heaps of bad info and bullshit marketing on the cheap end of led.
I’m sure there are those who still deny you can grow awesome buds under led.
Fact is you can with lots less electricity.

If you buy from a reputable dealer like Timber, you’ll get that information on plant spacing from fixture when you purchase, so you can set your canopy right in the Goldilocks zone.

They look like they're doing amazing! Do the plants that are not centered with the light tend to grow at an angle towards the light source or do they just do their thing?

When I was going for the lights, I was just thinking about future use and making sure my light footprint was covered. Never really back tracked on the fact that I was still using all four for the one plant lol.

That and I'm beginning to think I unconsciously formed an idea in the mind stating that it could handle all the light considering I've seen photos of 1 plant grown with 4000 model LED boards. As I type this though the logic unravels due to reminding myself that those models have dimmers for a reason...

Anyways, now that I've learned a lesson or two, I'll make the adjustments when Enigma wakes up.

Glad I did decide to run with my one bag seed instead of waiting for seeds to come in so I can learn some lessons prior to growing the seeds I paid for!

I could definitely see that. The hobby has been around forever and with how long people have been on the internet sharing/researching, there's bound to be more misinformation versus facts.

The Spider Farmer boards came with manuals describing the light distancing as pointed out earlier.

I was skeptical though because I thought plant was stretching when it was a seedling despite having all 4 at the right height and so I've been adjusting myself since. However, checking images of my seedling, it wasn't stretching and I was just worried. Another noob mistake that I'm learning from.

They only tend to tilt towards the light as seedlings...these are old enough to grow straight up. Yeah, your money woulda been better spent on a really nice light big enough for a 4x4 on its own, but I would be lying if I would say I have not done the same during this whole thing one way or another.

See, my seedling did that when it was young and I just assumed it would try that throughout growth. I'll remember for next time.

I definitely wish I could've spent the money on a 4k series light for the tent, but some us just gotta work on a budget. $360 vs $560 is a huge difference and allowed for me to set myself up with other equipment.

Already want another tent though, but the wife would kill me, ha! When it's more realistic though, definitely gonna have a larger light for another tent.

Gonna run these boards into the ground first and make them worth the money. It's nice to be able to move and adjust the individual lights though. Plus, I got a little angle action on each light so that it angles inwards towards the plants and provides some good side lighting.

Finally got the time in and was able to change out the Coco Loco with a new 50/50 mix of pure coco coir and Coco Loco.

It will now be dubbed as Coco "Not So" Loco.

Anyways, I also ended up turning off three lights in the end as I was doing things.

This is what Enigma looked like right before the lights went off and I finished everything up. Sorry I didn't take a pre-LST picture.

Hopefully the new soil mix and light adjustments give her a lighter green and the yellow new growth stops being so vicious.

Bonus picture! As of today Enigma is 29 days old from germination. Looks like it was still trying to tap into the bottom of the 5 gallon fabric pot! Can't imagine what it's gonna be like as it grows.

Brief update on Enigma.

I know it hasn't been long since I made the changes, but quick summary:
Was having issues with burnt tips and highlighter yellow leaves for new growth.

Adjusted the soil from 100% Coco Loco to 50/50 Coco Loco and pure coco coir to address the excess nutrient issue causing the burnt tips.

Adjusted light fixtures so that only one is operating and was placed 26" above the canopy versus 4 operating and 34" from canopy(recommended from Spider Farmer is 18"-24" for veg). This was done to address the discoloration on new growth.

Last post was the day I made the changes, here is today.

So far, I'm seeing that the burnt tips have stopped appearing on fan leaves. Obviously those that had the problem are stuck with it, but it's either stopped or very slow now compared to how it was. Very happy to see this.

As for the highlighter yellow....it's still around, but I'm probably being impatient as the growth that has it will need to recover and revert to the green. At the same time, I'm going to probably have to wait for more nodes to develop to see how they are responding to the light change.

Other than that, appears to be growing at a healthy rate! Still no signs of sex though, but still early.

Any feedback is appreciated! Especially information on the highlighter leaf problem and what I may be in for. Just want to see that my mistakes are fixed and I raise a healthy plant!

Have you tried just flushing them with PH water and checking run off? Could be a lockout happening.
Seems like a flush would be unnecessary considering I just potted it in the new mix and the burn growth has pretty much all stopped.

Not to mention I don't think it'd be this far along if a lockout was occurring and I'd see worse symptoms such as more leaves showing burnt spots, stalling in growth, and greater discoloration amongst total growth.

That highlighter color always disappears and turns into green as the fan leaf ages as well. To my knowledge, nutrient burns don't reverse. When I think of myself being the plant, I think I couldn't handle the light it was given till it's big and why the color shifts with age.

I just don't know how many nodes have been affected or how long the trend of yellow to green will progress.

Yeah I didn't read the second page.
Sorry.

No worries! Thanks for the input though. I definitely was on the verge of nute lockout with 100% Coco Loco.

The PPM on the runoff right now is about 900 with a PH of 6.0 (compared to the 2000 of just Coco Loco) and I know that's probably a bit high for a plant only 32 days old, but it should handle for the rest of the grow. Still haven't added nutrients and only using RO water that's been PH'd to 6.2.

Definitely gonna start with a 30/70 mix of Coco Loco/pure coco coir for next grow as it's just so dang strong to start.

Wow that's hot like 4.0 EC

Supa dupa hot. I'm astounded that Enigma lasted 3 weeks in there before getting burnt out.

Not to mention all my other early mistakes, I'm surprised it's doing as well as it is. Very sturdy strain for sure, whatever it is.
 
Thanks for the...uhhh...words.
I'm glad I'm not the only person who noticed dickwads on this board will reply with some condescending bullshit and completely not help you. Like thanks for flexing on a noob, now how bout some tips or some helpful info. I doubt that your fucking lights are causing that unless their cranked up too high. It's probably too much nitrogen.

Update time!

Hope everyone enjoyed 4/20. I originally wanted to make an update once Enigma was showing pre-flowers, but it's day 42 since tap root and it's still holding out on me.

What got me to post this update is the medium issues still continuing. And some mentions about light issues as well.

For the new 50/50 mix of Coco Loco and pure coco coir, my first run off test with it came out much lower than before and I figured that was that. However, the largest, older fan leaves started to show nute burn symptoms again. Checking the run off...2200ppm. My first thought is that the filtered water stored in the prepped coco coir helped bring the initial run off down, but now after being in there it cooked back up.

Additionally, after making the light changes I definitely wasn't considering the reflective mylar and its effects. In the corner, Enigma ended up getting light burnt on the tips closest to the wall and the highlighter was still there. This only took about 24-36 hours to be noticed and I ended up sending back 2 of SF-1000D lights and scooped up a Vivosun VS1000 LED QB.
I will say, the difference in LM301D and LM301H is pretty intense, and the dimmer is the key. Now its at 24" with 25% intensity and now as in the corner, but kinda close. This is lower than the suggested, but even at this level of intensity I swear the light burnt tips are progressing and new growth is still showing some highlighter symptoms.

Here are some photos.

I have pretty much stuck to just doing LST, haven't topped at any point, and the only defoliation I've done is on leaves that are more than 50% burnt.

So, at this point in time I think a flush is now needed as suggested before. It's either that or I will probably go for the full coco coir with just some perlite and transfer Enigma to that. Then use the Foliage Pro nutes I haven't even touched cause Coco Loco don't need no boost.

Any advice, suggestions, or tips would be appreciated! If you need more photos or need more information, let me know.

I've looked into them and I always see people saying to go for quality, but it's pricey.

When Enigma was younger with waaaaay more light power (four 100 watt lights all at 100%) and 100% Coco Loco @ almost 3000 ppm. Somehow only began to show highlighter symptoms and nute burn after 23 days under those conditions and it still hasn't fully taken over.

16 days from tap root:

23 days:
IMG_20210402_064743.jpg

Regardless, I'd definitely like a light meter to dial in what the plants enjoy. After doing more research and thought, I think I will flush the medium cause the root mass would be too risky to move to another pot.

After the flush, I'm just gonna go by the manufacturer recommendations and go from there.

If the problem was just light, dont fix anything else!

It wont magically green back up but wont matter either if you dont burn them any further.
