I never got around to ordering the UV so no idea on it.
I have noticed the worst areas start out up top, but under the canopy seems to be in better shape.

So I've gone ahead and dropped in a 4th board, staggering them running @ 120w about 22" above the canopy.

I went ahead and made a rez @ almost full strength,, 2.18EC.

I figure I'll let it go and see how things look in a week.

Monitor things closely my friend. If each of those boards are 220w each you've got 880w overhead. That's a considerable amount of output for the footprint they're illuminating. I'd bet my day's milk money the upper portion of your canopy is suffering from light burn. If you notice on HLG's website none of their lights are over 650w designed for a 5x5 footprint. Increasing the output beyond that would produce too much output causing unwanted light burn. Couple too much light with a high ec and that could be a perfect recipe for crispy leaves. The only reason I felt inclined to post this is because I know how much work you've put into your garden. I want your harvest to be successful as much as you do. My final thought here is in the form of a question: If changing the fertilizer from jack's to the flora trio didn't offer any improvement and the problem continued do you believe the issue is nutritive or environmental? Just a few ideas to knock around in the 'ol think bank

The boards are only running @ 120w each, so I've only got 480w going atm. I just changed that today stepping it down from 660w.
I do agree the lights could be a contributing factor to my issues, but honestly I've been having trouble in flower every since I switched to Jack's even under hid. About the only thing I haven't tried is feeding @ the recommended rates.

As far as lights go, I don't think I'll have anymore stress due to them. I'm right at 32k lux across the canopy so I'm definitely not over doing it there anymore. I used to push 60k+ under hid.

@jonnynobody
What temps are you running btw?

Oh snap dude. 480w is perfect. I would have to agree with you. I don't think the lights are going to be any issue at 120w each. In that case I'm definitely excited to see your full strength results. I bumped my ppm up to 850 after the rough transition to flower at 600ppm. Temps are 82F. AC runs from lights on to lights off. In a couple weeks I'll be back on the free AC program courtesy of mother nature's cool nighttime temps. I have noticed the plants do not drink as frequently versus growing under HID's. Some will go 3 days whereas under HID it was reliably every other day like clockwork. Twice a day on 2 monsters I had going. If the increase solves the problem I'll follow your lead. It really seems like they just don't drink as much as frequently so an increase in fertilizer strength is logical and sensible under these conditions. I start chopping on wednesday so I can't test the full strength on this flower cycle, but I will be running full strength on the next (pending your results of course). And if the jack's doesn't get you back on track at full strength try the GH flora trio start to finish and a bottle of cal mag. It's excellent fertilizer and performs reliably. I had things looking good under HID but all LED has definitely been a learning curve this cycle. Onward and forward - it's the only way

It's been a rough go this time around, but I still expect to clear 5-6# of quality flower. Compared to the last cycle there's definitely room for improvement.

The GDP has 3ish weeks left so I decided to get the UV up and running.






And all 4 seedlings are doing well under 30 watts.

Have you seen good results from the increase in ec?

6 days since flipping to 12/12. Just put them under the net to let the shorter 2 catch up. Thinking the net will be more than full by the time the stretch is over.
Not too bad looking for 4 ILGM seeds and some Amazon led's.



Hoping to fix a Mg issue by raising ph from 5.8 to 6.2. Feeding 1.8ec Jack's 321. Running 670w @ 18" atm. 36-38k lux.

Sounds like we're battling the same problem. This conversion to all LED is different. Ratios and ec that worked under my T5's do not provide proper nutrition to the plants under LED. I thought I had a calcium deficiency. It is actually a nasty mag deficiency. I have only experienced a mag deficiency once and that was years ago with gg4. It was just mag hungry strain. Needless to say I'm not good at identifying a mag deficiency. After increasing my ec I had more tiny dot like rust spots forming on 2 plants that were not there yesterday. Looked up mag deficiency after seeing the pale yellow leaves with the dark margins. Tiny rust spots, stunted growth, damaged new growth, and yellowing leaves with dark veins are apparently all telltale signs of a mag deficiency taking hold. Added 1.1g/gallon epsom salt to the res. Watered all the hydro plants with the new juice. I'll pop back in to post pics of my leaves showing the deficiency. Dam phone won't upload them for some reason.

Here are the pics of the plants affected by the mag deficiency. The little rust spots are hard to see in the pics but they're there. Yellowing leaves with dark green veins. Fried tips on new growth. This is what happens when a mag deficiency gets nasty. The pics of these 2 plants are the only ones in the garden with this issue. However, the 3 blue dreams are starting to show very early signs of the same problem. I caught this soon enough that the rest of the plants should suffer no damage and the 2 that did should make a rapid recovery. Hopefully all will be right with the world in 48 hours.

The rest of the garden. All looks good. Just the 2 most sensitive plants have been affected.

Yeah this Mg issue has been a problem every since I switched to Jack's but the LED's definitely seem to bring it out. My last harvest was crispy by the time it was finished. Probably one of the worst I've had so far.

I tried adding some Calimagic a few weeks ago but it just made things worse. I'm hopeful that it's a Ph issue. If not, I'm basically out of ideas at this point. But, I think I'm on the right track @ 1.8-2.0ec. Everytime I've ran anything less I've always had a deficiency problem.
If the 6.2ph can get the plants to uptake the Mg I wouldn't have anything to complain about.
Fingers crossed.

Yeah, were definitely having the same issue.

It's only been a few days since I raised the Ph but I haven't seen any new spots/discoloration show up so I'm hoping I'm on the right track.

After tucking some leaves I realized these are some of the better looking plants I've grown so far. Hopefully things keep heading this direction.

I've been wondering why it is my pictures have been looking like I was still running HPS. Didn't realize this new phone I got a month ago had a filter turned on in it.
I got it turned off and can finally see some real colors now.
Btw, who really needs 4 cameras in the first place??

I went ahead a mounted my other 2 boards to get a more even spread for flower. Lights are @ 14" running 655 watts total (about 50% power) with an even canopy reading of 37k lux on day 9 of flower. 1.6ec/6.2ph Jacks 3 2 1.

On point. My last harvest doing all LED was the worst I've grown in years. Deficiency after deficiency running the same ec I ran under mostly HID lighting. All LED is a different ball of wax vs HID. Good looking out on the higher ec. I'm giving it a try tomorrow on my new res. Your plants look incredible running the stronger nutes. I hope mine look as good as yours in a few days

It's day 21 since flipping to 12/12 so I'm going to strip the leaves. It's that cold, wet time of year so a little help lowering the humidity for later flower will help out a lot.
New reservoir mixed up today @ 2.2ec (1.9 jacks/.3 Calimagic)


Time to find the scissors. Got quite a bit of foliage to remove.

Day 28 of 12/12.
I got lazy and ended up only defoliating 2 of the 4 plants. Figure I'll let them ride and compare the differences in yields between them.
Still cruising along @ 2.1Ec.
