I’ve gotten good at providing info fast let’s go,
2x4x8 ft closet grow.
Strain: purple Afghan Kush by Dina fem
From clone we are probably 10 weeks old.
closet has 180 cfm fan secured to the top of closet door. There is no intake.
Plants spent roughly 9 weeks under 96 wats of t5
A week ago I dropped the serious sunshine on them that being the electric sky 300 v2 at 50% at 3.5 ft from canopy.
Things went well for a few days and growth did explode a tad.
then I saw what you see in the photos.
I thought it was magnesium and I saw a little calcium as welll so I hit them on there last water with 350 ppm camg Botanicare.
This was 2 days ago and the plants will be coming up for a watering tomorow.
Since there last watering nothing has progressed negatively.
opinions of all kinds appreciated this is my first time growing with an led of substanc
first 2 weeks in peat plugs
Next 6 weeks in 1 gallon roots organic originalonce the 1 gals were filled they went into 5 gallon containers w/ coast of Maine growers mix. all the while receiving ewc teas here and there as well as regular pro tech silica splash of super thrive here and there as well as coconut water and aloe Vera.

great white inoculation for each transplant as well as a few compost ewc great white too dresses in the 1 gal.
Ph 6.3-6.7

first three photos are today
Second photos are when I spotted the light stress or deficiency or yet to be detirmened

I will note it seems to be very local as far as it just effecting one section of one plant ... could mean the others aren’t far behind.

no stress in all blessin hope everyone’s having a great Monday!

Your plants look ok.
It's not light stress at 50% ~150 watts 3.5 ft away.
Looks like start of magnesium deficiency.

Thanks man I do agree plants are doing well.
start of mag deficiency I agree and I watered in camg by Botanicare at 350 ppm last watering aNd nothing got worse and new growth looks decent so I’m going to just carry on with camg for the next several waterings and pay attention to response.
I do have some magamp maybe that would be better.
i worry about cranking the light back up but maybe I should as I’ve had it dialed back to 30% or so since these issues arised

I’m kinda shocked I have a mag issues using fresh dirt with things like fresh lobster compost ewc molasss aloe coconut water. What would be a suggested organic route for this issue?

I’m considering continuing with the ca mag or maybe even switching half to half tapmy tap comes out 250 or so....
I’ve been trying to research good bokashi topdress ratios......... I’d like to get a nice layer of Santa’s beard up top

Try to bring up temps to between 81-84 and keep on giving some calmag but not too much. Id say its transpiration related, higher temps and they drink and feed better. The es spectrum is quite red/flower leaning, if you could get some blue/cold light in there it would help open the stomata aswell.

How fresh is the soil? Perhaps the amendments haven't broken down enough yet? As for supplementing - personally, I'd use Epsom salt for the mag, instead of a cal-mag blend.

Thanks for the info I’m going to bump temps up a bit.
I should mention transpiration has been on my mind the way my set up is.
Maldonado I had to ward off spider mites to I’ve been really clogging upstomata last 2-3 weeks but I’ve layed off. I’ve started to leave the closet door cracked. And plants seem to be responding

The plants went from a 1 gallon into 5 gallons fresh coast of Maine growers mix where they’ve now been for 2 weeks. Borderline feed time in my opinion. I’ve been running ro the whole time.


sounds like the consensus is use Epsom? What ratios do you gentlemen use?
I imagine this is because we don’t want to overdue the calcium with Botanicare

I think the cal mag 350 ppm - 500 or 700 scale ? might be a low dose to deter deficiencies starting and you would double that dose when you see clear signs of deficiency.
As said above get Epsoms salts, it's cheap as chips!

A tablespoon per US gallon.
Mix the dose in a small amount of warm water to dissolve the crystals first, say a pint then stir it into the rest of the gallon and water plants.
I just chuck a sprinkle or 3 of Epsom into my soil when transplanting, nothing scientific lol

Great. Growing with leds environment gets much more important: leaves are much colder than with hid so they dont like to drink so much. You can control this by taking vapour pressure deficit into account, id really recommend reading up on it. Basicly: 81-84F, everytime you up light levels you may need to adjust temps a bit and maybe calmag or epson foliar. Many a led grower have been chasing this kinda problems around. Some blue light might also help opening stomatas. Usually when the plant is bigg enough and in flower its easier, its already going full speed ahead and drinks more.

Also do whatever moflow does, he is the cold temps voodoo master around here.

Super interesting man thank you.
im out and about today to day off smoking and vibing. My vpd calculations rough calculations are based off canopy temp so I’m going to get a thermalgun today......
I’m not gimme wayer with camg next watering will be magnesium sulfate.
@ 1 tablespoon per gallon is what it sounds like. Hope that’s an appropriate dose for my situation I may cower and go half strength. Never used Epsom

If I were running co2 I’d garuntee raise temps so it’s news to me about running higher temps with leds this should help me.
