Well its been 3 days since I added the cali magic from gh to my feeding and I cam say the problem has not seemed to get any worse but not any better. Affected growth will never heal so I've been trimming a little every other day. Sigh with as many years experience I have hard to believe problems like this still arise...liveand learn..

Any comments on the pics would be greatlyy appreciated. Thanx

I believe I already mentioned that what's been affected won't repair (remember, Ca is immobile). I still think you should be using a Ca-only product, not a combined Ca/Mg product.

I agree that the whitish spotting resembles spider mite damage.

It's more like rust colored. But noone gets spidermites in my area like i said its too hot and humid here they don't exist.... Maybe another pest? Fungus gnat larvea?

As for cal mag what's a little extra mag going to hurt?

It can and will throw the available Ca balance off, not to mention it's simply not necessary.

Bro hate to say it but you got spider mites as for whats the little extra mag going to hurt well it will hurt your N uptake

I mention this over and over to help growers determine def or toxicity
write this down lol macro nutrients NPK to determine if plant is having any of these issues the problems will start on lower leafs and lower plant
Micro nutrients is opposite and will start symptoms on upper portion of plant

what i would do if i were you is first thing treat plant for spider mites 2 treatments in 8 days but most importantly your going to need to completely sterilize your room meaning lights walls everything in your room needs to be washed with clorine / or pine sol
light bulbs everything

now purchase neem oil / safers brand any insecticide non aerisol
something you can make a batch of personally i would make enough as to dump plant completley upside down into the solution moving it up and down for a few mins carefully placing it right side up and in dark place till there dry then resume growing 2 times this is needed 3 -4 day intervals forget spraying plant they will come back you need to dip plant top first into solution

most of the leafs will remain ugly and never come back monitor new growth for any spotting ,

now my guess is plant has this occuring lower middle of plant and up right ????? this suggest to me if its not spider mites which i am 100 percent it is it will be micro nutrient issues possibly iron and Zinc hope this helps cheers rust spots tell me that it is both

Thank you for your insight but i will mention for the third time spider mites DO NOT LIVE or THRIVE in my area which is a tropical region with nearly 100% humididty every day of the year. I undetstand all u Midwest and west coast peoples obsession but it is not relivant to me.

Also I'm not so conscerned about N uptake this late in flower...cal mag is not going to hurt this late in the game.

Now with that bieng said leaving spider mites out of the eqaution. What does the def look like to any of you? I'll keep u all posted. Full pics to come.
Thanx

So ill get some neem oil and try not spraying the buds sites.I didn't relize thrips were flying insects and now that i think of it I have spotted a couple little flying critters under the canopy; just out of the corner of my eye. Thought they were fungus gnats and not wnough of them to do any real harm...

I dont think its thrips should be easy to confirm tho there would be little slender yellow bugs crawling on affected leaves if you do find thrips and your already 4 weeks in personally i would ignore it, they dont do much damage at all maybe just spray were you see thrips no sense spraying down the whole plant with something for thrips IME.

Also thrips make tracks not spots those look like spots almost from a mist that got on the leaves have you sprayed them with anything?

AHA!!!!!!!!!!!! COOTIES!!!!!!!!!!...maybe...:biggrin:
Although I do have to agree with Bongtoke there that cooties (Thrips) leave streaks and not spots. Better make 100% sure of what the pest is before you tackle it. Might end up doing more harm than good.
I used Pyrethrin. It's an organic obtained from the Chrysanthemum flower. I sprayed everything and I got some browning of the pistils/hairs. I thought that one of my girls got damaged by it due to some leave yellowing but it's on the mend. I did 2 applications of that plus I used Neem Oil in the soil. Part of their lifecycle they drop into the soil to pupate so the Neem Oil was mixed with water and poured in to take care of them.

The most common killer of them is Spinosad and a lot of people swear by it. It's an organic as well.. I forget the name of the fungus it's obtained from. I cannot find it in Canada so I'm waiting for some via the Ebay route........just in case there is a next time.

Please be sure you know the enemy, I can't stress that enough..

Good Luck

did you end up getting an accurate ph of the soil IME if your using dolomite at around 2tbs/gal of soiless your ph should be coming out higher than 5.8 I usally shoot for a runoff ph around 6.5

I'm 95% its not thrips...
I was reading my AN connoisseur bottle today and aparently it has ..1.5% calcium in it already prob should have read that before....unless my strain is a cal hog which is possible. I think i will look further into a pest priblem but i don't c much of any signs , other than the rust spots of an infestation.

What is your method for removing thrips sir? My google hand is not working it burmt out .
pics just a little too fuzzy to be 100% but having had thrips and mites I would say NOT. The damage looks more like mites but the "dots' seem just a lttle too big for mites and thrip damage just looks different, at least the ones I had.

As to the cause, sorry don't know. maybe more pics would help ascertain.

Whole lot looking better with more food. Damage is more pronounced under the light, growth on the outskirts is way lush and deep green very little damage. Still all in all looks ok and im hoping to get the through this run and clean up really good before next run.

No I havnt went to get the soil ph tester yet...real busy lately. Runoff steady at 5.8. I can also say I used more dolomite than that per gallon. I just eyeballed the amount I used:biggrin:
 
I thought it was spider mites at first, but like medical said, the dots are too big. Thrips are easy to kill, but they usually have more ragged and random spots. For thrips just get some spinosad. Monterrey garden insect spray is a good brand name. Its organic and a bottle will set u back $15.
