Fastbuds LSD25 boron maybe?

[McDee]

Problem: Slow growth spotting and dying older leaves. Light in color

Medium/grow method: Pro mix bx with coco loco. Fabric air pots 3g.

Feed: and supplements used: Fox farms trio, Advanced Nutrients voodoo juice, microbial munch, b-52, cal-mg, ph up. 25% strength.

water source: R/O.

Strain/age: Fastbuds LSD25, 22 days old.

light used: 2 autocobs and platinum led p150.

Climate: In 2x4x5 tent, lights 24/0, fan, intake/exhaust fans.

Additional info: Have a gg4 with same feed and it's huge, no issues. Thought it might be the lights but soil was very dry so maybe boron?

It's normal for a few bottom leaves to turn yellow and die off.The last picture looks like magnieseum def and if your using coco you will need extra cal/mag.Also you might want to up your veg nutes to give more nitrogen to green up those lighter green plants.I would remove those bad lower leaves because they are pretty much gone.

Ok, thanks. Hope that's all it is, was giving 3ml/g, but up'd to 5ml yesterday and feed them. Cut off those leaves and lst'd them with some supercropping. I have a gg4 and gsc as well they are fine, nice green to them gg4 is huge I topped last week. Why would they be fine, and such a def in the Lsd? Not questioning just trying to learn more. I had little under feed her just cause didn't want to over feed.

It could be one of a couple things. It looks like a ph issue, it is sometimes caused when PH swings up and down, or is too high. pics are close enough to tell for sure, but do any leaves have tiny white spots? it almost looks like the do in your pics, if so, you have spider mites and/or root aphids, which can cause the same symptoms.

Here she is before she got tied down.

Pop22, thanks. Oh was 6.6 I have it at 6.4 now. Don't think mites here some close ups.

Only thing I can think of is I have a co2 diy. When it was new it would miss a good bit, well fan would blow it. Lsd was last plant and I wonder if it was blowing my yeast/sugar/water mix on my plant. It would expand why only one effected. Would that kill some leaves. Like o said giving my gg4 same water and it's HUGE! I have it topped, supercroped, and lst'd.

Almost like plant is living off leaves not nutrients.

--McDee, something is FUBAR in that pot, .. I'm with pop22, it's very suspect for badly off pH,.. I see multiple defc.s', top to bottom,... an actual in-pot pH is called for, or at the very least a run-off test of pH and ppm's from water only; it's a crude estimate, but it will give a ballpark indication if the pH is badly off, and if it's being caused by nutrient build-up or not,... if other plants are fine from the same nutes, etc., then something went tits-up with this one,... your feeds, at 25% are pretty mild,.. any idea what ppm/EC that measures out to? Do you water/feed to significant run-off? this is a must in soilless, especially with coco,... coco is a huge Ca hog until sated, are you using only 25% str. Ca-Mg as well?

Ok, I just feed them yesterday so dont have run off ph. Don't know how to get ec. It's only 30% coco and was using 3ml calmag raised it to 5ml. What should i do in the mean time, I won't feed until like most likely Saturday?
