Whats up with that purpleish/brown stuff?

Hey RIU!

I was just wondering what you guys think is going on with my babies. I've got 2 month old MK Ultra clones... I noticed a couple days ago that the leaves of one of them started to develop small brown/purple spots. I have been giving the clones 1/8-1/4 strength 10-10-10 plant food with every watering (every 2 or 3 days) starting last week. I was thinking of switching over to fox farms grow big for nutes... good idea? Anyways....

pH of the water is balanced at around 6-6.2.
Temp: 70-78 F
RH: 30-50%
Lights: 8 x 43-watt 6500k CFLs

Clone #1


Clone #2



I am thinking that its a deficiency, but I am looking for some second opinions! Help greatly appreciated!

Great... hahaha well i hope we find that answer quick...

this vid should answer your q's

looks like nute burn to me.
You probably dont want to give them nutes on every water.
there still babies and will only require nutes maybe once a week.
Id back off the nutes and feed PH balanced water and see how you get on!
usually with a deficiency you would see it in the whole plant but that seems
to be working its way up the plant. Im no Pro but looks like nute burn.

imma get on it!

This is definately overfertilizing. Flush and cut down fertilizing untill it´s fixed.

Like I said though im not 100% sure.
they look a very light green which makes me think there could
be a deficiency somewhere there.
Maybe there getting to much of some nutes and not enough of
something else!
Id try the flush first with and feed only PH balanced water and if
you dont see no changes or they get worse maybe try the nutes at like 1/4 strength
every other feed and see how you get on.

Doesn't look burnt, looks deficient from what i can see. Leaves are turning yellow purplish/ grey tint, check it out man ~~~> https://www.rollitup.org/view.php?pg=faq&cmd=article&id=588. Judging by what you said, you might want to up the nutrient levels slightly since you've only been hitting with a low solution. But like the dude said, you normally dont want to give them nutes every water because of salt build ups. Maybe try giving them a good flush with phd water, then after that up the solution slightly and see how they react.

Alright! Thanks for the help everyone!

Wait... so either its over fertilizing or not enough fertilizer?

From my experience and the FAQ plant abuse chart, from my previous post, it looks like at least Nitrogen, Phosphate, and Potassium deficiency.

well i figured out what my problem was. the soil of my PH was off. test the water u put into it then test the runoff. i put in 6.5 and the run off was 5.5 so mine was a Mag deficiency. if the ph goes under 6.0 it will lock out your mag and other nutes. if its over 7.0 it will lock out differant needed nutes. so u gotta try to keep your soil around 6.5.

you know what... that makes so much sense! hahaha imma rebalance my water and see if that helps.
