why the yellow

here is a picture.

these are getting close to done but my question is why the discolor yellow and brown spots? is it normal can i make it do it less?

thanks

Are you by any chance growing in Fox Farms Ocean Forest soil?

It looks like a type of lockout. Meaning you have an excess of a certain mineral that is locking out other minerals making it look deficient. 99% of the time it's due to either Potassium or Phosphorus. I can't diagnose it without knowing more about your nutrient recipe and media as well as environmental conditions. Message me if you want to try and figure it out.

no not fox farm.
I'm going to send you a message but i will write what i think you want to know here for anyone else that might happen upon it.

this plant is 1 plant in a aerogarden base (1 gal) with a air stone
150w HPS light kept about 6 inches away
i have 1 of those exhale bags above
nuts I'm usinger 1 gal of filtered water 5ml pro-teckt + lucas formula 8ml micro 16 bloom but have been adding 2.5ml of liquid cool bloom and 2.5ml of technaflora magical. ( why the cool bloom and magical... i really don't have a good reason expect i read calcium and magnesium and potassium were important)
ppm of this is about 1050
ph is kept between 5.8-6.2 with GH up and down
the temp is about 80 lights on and 70 lights off.
it is 11 weeks today.

i ran some florakleen for a few hours last week because the guy at the plant store said i should do that once a month.

i am also attaching photos of my next plant (call it 2) in line. it is in a waterfarm with an add air stone in the bottom. same nuts, but under a kissel 150 purple. its at 5 weeks. it docent look great and i did a real bad job with trimming it. i was going to keep it as a mother but it just got way to bushy. now it looks small and like it might not grow tall...

also i attached a picture of the my first clone. that when the first set we are talking about is harvested will put under the purple and 2 moved to HPS. this one has some ugly on the leaves as well. it is being fed the same nuts but watered down to between 200-275 ppm

Aye. Looks like potassium in the last pics. Burnt tips are usually a sign of lockout from over fertilizing.

do you think i should stop with the koolbloom and magical?
should i do the florakleen for a few days? or maybe just plain water?
do you think they will finish or should i just cut them now?
i think it should be done in about 2 more weeks if it finishes

I would just flush with water and hold off on nutes. If you're close see how it goes over the next few days. If the yellowing doesn't get any worse let it go.

thats extremly deadly yellow mold you should send it to me for immediate disposal

Yellowing towards the end of flower is normal, however, that looks more like over fertilization...

The really dark green is too much N and the splotchy burnt orangy spots are from lock out of P or K.

In the future do yourself a favor and run a much lower ppm, blindly following a recipe is the difference between betty crooker and grandma's homecooking. Plants like to be seasoned to taste, lol.

Also, I'm not sure lucas is meant to be run with a pk bosst like koolbloom.

Just my opinion.

I find that running a lower ppm in flower enables me to actually use a bost and reap the most benefits from it. Not to mention the lower ppm makes for a tastier and cleaner final product. Not going over 700ppm in veg and trying to stay under 1000ppm in flower lets me flush once before I switch to 12/12 and then I feed only water the last week in flower.

Here is that strain I was telling you about. Our Purple Fire.. --> Foxtailing.
