too much light (lime green)?

hey riu!

i am flowering three plants in my stealth cabinet, and the plants are very light green. (journal: 2 Blue Mystics and a Dynamite)

they were healthily green when i put them in flower, and they slowly started to get lighter, as if bleached by the light.

i currently use pro blend pro in veg and pure blend pro bloom for flower. i put half teaspoon in a gallon of water, with a half teaspoon of super thrive -- i also make a half this, half water solution for foliar spray. water is municipal, but left out at least 24 hours.

should i increase nutes? change nutes?

thanks!

Light green leaves is usually low Nitrogen, Which happens during flowering.

thank you for a quick reply, my worry is that i just got finished with a harvest in the same setup, but two plants. one was perfectly green the whole way through, and one did this lime nonesense.

the one that was lime the whole way through tastes much worse. its a different strain than the other plant that was in flower, but a clone, and ive had it before, but this was shitty.

i dont want this to happen to my whole harvest.

do i look for a nitrogen-only supplement?

wow, i found this link in another thread (https://www.rollitup.org/view.php?pg=faq), and i think it is sulfur deficiency, but they make no recommendations with the aliments.

This isn't the problem with your plant, but you put 1/2 teaspoon
of superthrive to a gallon of water??? I thought it was supposed
to be a single drop per gallon, that stuff is loaded with hormones,
and all kinds of not so amazing stuff... its great in small quantities,
but it sounds like you're over doing it just a tad...

BTW this looks more like an IRON defic....

Nitrogen starts with the older leaves and works
its way up because it is a mobile nutrient..

This is an immobile deficiency it seems because it
is starting with younger leaves, I would say either Iron
or calcium....BTW whats your run off PPM/PH?

ill check that next time i water -- what would one do in the event of an iron or calcium deficiency?

and has nothing to do with the amount of light in the enclosed area?

If it were from too much light they would be turning white. Basically bleaching.
Like coral...

To correct the deficiency, the next time you feed, check your run off PPM/PH

And add some Cal-Mag Plus from Botanicare, that would take care of most
of your micro nutrient deficiencies... With a plant that size you want your
run-off to be around 900-1000 ppm

agreed, that would be too much. I use just a few drops in 12 gallons of water because the stuff is just so damn potent. You may want to consider a very quick water only flush and then get right back to you tried and true feeding schedule, less the overdose of superthrive...

prescribed dosage: one drop per small cup full; 1/4 teaspoon (1ml) per gallon. so i should have been using half a capfull...

i also went to my friendly neighborhood grow store, and the guy guessed that it was a ph issue, due to the even discoloration. he suggested me flush it with 3 gallons of 7.0-7.5 ph water, and measure the run off.

i'll be doing this shortly...

so it turns out that i shouldnt be using super thrive in flower, and i've been under nuting. combination effect: my current situation. so i flushed with PH 7.0 water, and am wanting to add nutes today.

so, in an effort to not use potentially bad information from the aforementioned source, would someone please tell me what they use for their solution ratio for flowering plants. I am using Pure Blend Pro Bloom, and i will be adding it to gallons. also, what should the ph be for the water? i have a tds meter if measuring that is more accurate than say, a teaspoon. i'd have to get ro'd water, which would be less easy, but doable..

thanks!
