Nitrogen excess, disease, or just time to transplant?

Hey all so I have been playing around with some bag seed, pheno hunting and decided it was time to FIM one of my plants, well I did and shortly after it seemed to be showing signs of what seems to be a nitrogen excess (dark green, clawing ends) but I was wondering if it could be a disease as the other plants around it are on the same feed (Lucas/h3ad formula with added silica comes out between 750-800ppm 5.75-5.95ph) and of the same strain (whatever it may be) and are flourishing for the week they are in (week 3).


Like a dummy I didn't wash my hands before pinching the top leaves off this time so disease isn't entirely out of the picture plus the issue occurred a few hours after the FIM.

I would of thought it was time to transplant but a buddy told me to let it finish up the week before transplanting so I took his advice while I don't think this is the issue it's not impossible.

Mars hydro tsw2000 which is 18inches away at 100%
Environment stays around 70° with 10° dips and rises in temp depending on the time of day and outside Temps and when lights are on (I'm in a detached garage)
RH stays pretty solid between 50-60 sometime drops to 40s provided the humidifier gets refilled in time.

I did flush with recharge this morning just to see if it will make a difference.

Move that particular plant away from the intense light for a while. See if it perks up.
If you are running that light 20hrs on that's a DLI of 79! Feck!

The generally accepted guidelines for artificial light PPFD in flowering during 12/12:
PPFD of at least 510 micromoles/m2/s-1 for the low end of optimal intensity
PPFD of at least 800-1100 micromoles/m2/s-1 for optimal lighting WITHOUT additional CO2.
PPFD of at least 800-1500 micromoles/m2/s-1 for optimal lighting WITH additional CO2.

You are probably giving too much feed for small plants.
Maybe transplant it shortly too. What medium are you growing them in?
What do the other plants look like?


The tsw 2000 at 18" away is for Full Blast flowering.

You only need ~ 400 umols in veg over 20 hour period

Here's a handy tool. Converts ppfd/umols to DLI

Thanks fam, this is my first time working with leds on my own so my dumb ass just pumped it up lol definitely will turn it down. And that tool looks really neat

The other two plants in the tent are taking the feed quite well but the high ppm is purposeful as I have a large quantity of bag seed and am trying to ween out the not so resilient plants and I've seen this strength work for others for that purpose.
Feed is
1.5ml armor-si
2ml calimagic
6ml floramicro
9ml florabloom
1 gallon water usually add more to dilute to desired ppm

This plant having issues is in 100% coco until it transplants to 70/30 coco/perlite, there is another plant in 100% coco doing great and I recently transplanted the third into a 3gal with 70/30 coco/perlite.

After it's flush with recharge it did perk up a good bit.

As long as I had the opportunity to check-in and water frequently, I'd be inclined to use more perlite when the plants are small, then less as they got bigger. I hate having young roots sitting in a 'too wet' media between drinks.
Good luck.
