Yellowing / Spotty Leaves - Multistrain

[ceosam]

So recently I overcame to what seemed to be a them needing some more cal/mag which made sense considering my medium is coco and they were getting a low dosage.

So everything greened up really nice and I flipped the lights.. Now I've got some yellowing / spotting on the leaves. The spots almost look like spidermite scars but I am sure they are not. Also the leaves are curling down quite a bit.

6/9 Flora + CalMag + Diamond Nectar

PH feeding @ 6.0

Just flushed recently.... Temps are never above 75*F

Not sure what the deal is here, any thoughts? Some strains more than others but all have it somewhat.

What PH did you hit them @

 

[ceosam]

Always 6.0

it would be a good idea to inspect the roots... like maybe root aphids. i'd check the new shoots for russet mites as well. if nothing else but to rule it out.

check the run off ph + ppm's too.

Looks like your on to something... I see some BARELY visible (much smaller than spider mite) tiny white things moving around under the leaves... Very small.

Also noticed many flyers in the root area, which I would have thought and still might be fungus gnats which are very common in my area... But on my clone tray I see some white fuzz patches and very small fast moving runners.

I've treated with both a drench & light misting of Azamax (350ml to 30gal) and intend on putting some diatomaceous earth in the top of my pots. What else can a brother do? This is a new climate/area for me and am not all that attuned to the local pests. Help!

This is truly heartbreaking.

I have no option but to fight this, HARD. I've been reading the thread since MIway first suggested it and there seems to be a ton of speculation, etc.

I have Azamax & Floramite on hand now... Anyone care to share some of their first hand experiences in overcoming these bastards? I am prepared to be diligent, I just need a regime that works.

 

[MIway]

root aphids = imidacloprid

russet = abamectin


trick w both is getting complete & total coverage... esp w the ra's, which can be tough. but the above are the hard hitters which kill. effectiveness is in the application method. but if these bugs are the problem... some damage has already been done/crop wont ever b right. keep a keen eye on eradication for the next bump.

Pretty certain its just RA... "just"

I've got Merit 75 on the way, what other products are super effective? I have Floramite and Avid but I read it doesn't do the trick.

i don't think so..with RA the bottom older leaves die off first...new growth generally looks fine...

and before you go on and nuke your plants you should read this: http://www.times-standard.com/local...e-you-smoking-study-finds-pesticides-transfer

Just flushed recently....

what did you flush with?

coco should NOT be flushed without nutes or you wash away the food the plants need...

Wow, at first i thought this was root rot.
