LED too powerful ?

I dont think your light is the problem either..
but if you're dead set on the light being the issue then at least get yourself a meter so you can regulate the par.

Pics of your several ph meters and who told ya to try different light again?

Im not around them now but a few are Blue lab and a few are Aprea ( I may have misspelled ). Both are pen types , around 75/85 dollars.

It’s been a while but I’m pretty sure when I was getting light burn on my plants they didn’t shy away from it, just grow and turn crispy.

That should work
Again it just seems going thru so much stuff so fast is like you are trying to kill an elephant without ever shooting a squirrel
I couldn’t do what I do now years ago it took my decades to get it right but you don’t seem to understand the process
Anytime I find a pheno I even like I do three runs before I even decide to keep it
If I change things constantly I wouldn’t learn much
Find a method
Stay consistent
Then you will be able to grow dank
Even with that light

It's not a light issue......it's a deficiency, probably a micro-nutrient. Intense light will only make things worse faster, so don't try to push the plants until they seem to be doing better.

Hello
That makes a lot of sense knowing that everything changed when I got this light . Two grows prior , same media , same nutes, same everything and other than being airy, i had a good quality product. Are you saying the better the light the more “ imperfections” could be exposed ? When I talked to the manufacturer he mentioned ( don’t quote me ) that their LEDs are extremely close on their board and they ( again , don’t quote me ) intersect due to the tight pattern. I have only ever seen Pink Chinese lights so I don’t know how to compare but this light is extremely bright in my opinion.

@Herb & Suds was talking about a pH meter .. dont confuse the 2.

That’s a good point. I kinda thought the same thing ,’then I thought “ how much better could they be ? “ . My plants are like my old prom date. She wasn’t pretty but she got the job done.

How could you ask people one here to diagnose a light problem and you won't say what type of light it is. There are hundreds of LED's available and some are very different to others.
Saying that there is no way that plants are healthy till exactly week 5 then they become unhealthy because of the light.
Some other problem is at play!

Truthfully , I thought mentioning the name was against the rules. You are the first person to really ask. I am using a Next Light Mega.

Not light burn..I've ran 360w worth of quantum board and 100w side lightngin a 2x4 with 10" to the board at full pelt. No issues with light burn.

I have my 15 day old plants under a 120w quantum board in a 1.6x1.6 full pelt at 14" away with no issues.

You would need a multiple thousand watt light to have to run it 50" away and still get burn. That's just sounds bizarre. Just looks like nute burn or pH issues to me.

The fact that it's showing on lower leaves kinda disputes it being from lights.

As far as I can understand you water big coco pots everyday (til runoff or just a little?): Some people can make this work, not here though; it always gets our grow into problems. In any case if you're doing this you really need to check and maintain run off ppms in order to not get your media hot with nutes. Hot media will give you drying up leaves in tips and can cause lockout.

Instead of insisting that everything is absolutely perfect maybe give some details?
pH/ppm in and out of your pots leading up to week 5, what are your stable temps/rh and what is the light intensity (lux is usually ok).

Hard or soft water? Salt build up at a guess. I normally fush plants at start of flower when using Coco and hempty pots. either that or a PK issue.

I have responded to everyones questions regarding ph/ppm in the earlier posts. Temps are running 70/75 RH / 50. I have my LUX meter in storage so I’m unable to check that. The only reason I stated that everything else is great is because it is. I’ve been battling this for years and have eliminated most possibilities. I don’t always grow in coco. I mentioned I have grown in soil , coco and Promix. All the same results. I originally had five plants but it began to get crowded in the 2/3 week so I put one outside. Same Promix. Feeding it the same nutes. Same PH , etc. the only difference is that it’s outside ( and it looks great ) .

LONG VERSION : I posted a few months ago on her basically explaining I have been growing for 5/6 years. I started with a cheap Chinese light but quickly upgraded to a “ good light “. (I don’t want to mention the manufacturer). ALL my grows seemed to dry and wilt about five weeks into flower. Like clockwork ! It didn’t matter what I grew in , what nutes I used ,
Etc. My temps and humidity are spot on. Various strains ( 35/40) . I ruled out everything except for this new light I purchased. The light is a well known light and somewhat expensive so I assumed it was a good light. A few months ago the same thing happened ( week five of flower it was drying up ) so I called the manufacturer. I told him I have the light 24” from the canopy and he immediately said you have to be much higher although the light specs says 18”-24” in flower. I should have pressed the issue and ask why they recommend that height if it will burn your plants but I was so excited that I finally figured out my issue. I’m week five/six of flower and the light is 50” inches from the top of the canopy and the leaves are once again drying up ( starts with the tips ). I’ve looked everywhere for answers but I cannot seem to find anyone else that has this issue.
SHORT VERSION : The manufacturer advertises 18”-24” above the canopy and when I called they recommend I put the light as far as I can from the canopy. I know have it at 50” and the leaves are beginning to burn. I’m anal with nutes , PH , watering , etc. It has to be the light. I never knew an LED could do that ?

If you are sure it's the light and distance to its canopy. Try offsetting the lights placement. Move your plants slightly out of the lights Footprint.

I've read this thread over and see some inconsistencies and trying too many things at the same time to rectify one issue at a specific time @ 5 weeks.
I bet I could give you a better idea if you posted the mfg of your lights. There are many many variables among the different lights out there.

Lux meters don’t work on economy leds they only work on white light not red blue blue blurples. You’d need a par meter for that and they probably cost more than the light but it’s not a light problem IMO

Here’s what is happening the light you had prior sucked or not strong enough you fed and the plant ate slowly. Once you introduced a new light strong in par and everything else it started eating harder the temp went up most likely as well. Couple the light and the temp and likely the rh% the plants metabolized faster this burning your plants. dont follow feeding schedules as they’re pointless. They’re a simple guide or suggestion nothing more. watch and read your plants instead they’ll tell you what they need food wise. Us ec as well considering every nutrient company uses 5 or 700 scale but some don’t inform you of what they use. Where as ec is universal.

What light did you have vs what you have/using now?
