White spotting on leaves

This is an older leaf from the bottom of the plant so the yellowing is normal. It’s hard to see from this picture maybe but a kind of silvery white spotting is on some of the leaves. Tiny white spotting, almost silvery in the sunshine. The strain in Candy Jack. Grown in large pots outdoors. I use fox farms fertiliser, sparingly. Water out of the tap is close to 7.0 ph. And I know the fertilizer brings it down, too much maybe, I only recently started testing the ph. of our water.

Have you checked for spider mites?


Also if your using tap water be sure to let it sit out for at least 24 hours before using. Most tap water contains chlorine which is not good for plants in large concentrations. Letting it sit out will get rid of the chlorine.


Sorry dont have an exact answer but I have recently noticed same thing on mine but I am fighting some type of whitefly/ aphid bug… It seems any leaf they have spread too eventually gets like that and yellow up and die… Not saying thats what you got just adding my 2 cents… I will be following this thread… Have you applied any DE earth? It will stain like that… Have u checked under leafs for bugs.?

Thanks for the answers people. I’ll flesh out the support ticket questions. Plants are about 3 months old. In 7 gallon pots on my deck. They get 6 hours of direct sun, temps have been around 90 in day and 60 at night. Soil is 420 formulated for pot grown in northern California climate. Pots dry out daily, daily watering. I’m now adjusting the ph although I haven’t been up to now. Yes I check leaves for bugs or other issues. I had caterpillars which were eradicated using clove oil. I’m using fox farms grow big fertilizer at half strength, just switched to tiger bloom, half strength. It’s not a dire situation even if this one plant don’t make it I have a dozen more doing pretty well I, think. Just attempting to identify problem.

Ph is 5.5 going into the plants, runoff is 4.5 coming out. Not sure how accurate this is because I don’t know what the ph was before I just started testing it, meaning it might still be flushing out whatever came before?
Anyway here’s a picture of the plant. I got the stain wrong… It’s called Hash Passion.
And a better leaf picture. I kind of wonder if it might be something residual from the water; I was misting the plants awhile back.
2. While I’m here can I ask another question. Some plants are now over 7 feet high and starting to flower. They are in 5 gallon containers and I want to transplant to 10 gallon containers. Is that a good idea to transplant such a large plant?
Love, Joseph

Hi. Checking first pic the small white spots is a light triphs damage. But the yellowing is caused by another issue , it seems a deficiencie.
Till now the 2 problems are not too damaging , but if it will continue you must ask experts and solve.
My though is it will continue.
Good growing

Thank you, Teddy. The white spots are on the bottom leaves of plant where older leaves are turning yellow anyway, so I don’t think the yellowing is unusual the rest of the plant is ok. This is my first grow and I have 6 younger plants like this and 10 plants now pushing 8 feet high before any flowering has started. Could be good…

PS do you think it’s a good idea to transplant these tall plants at this point? It looks like they are crowding out the 5 gallon containers I want to move them into 10 gallon pots. Here I’ll do a picture of um…

They are probably tall and thin due to their receiving only 5 to 6 hours of direct light a day.

I found online pictures it’s triphs for sure, as Teddy said. Will redo an application of sprayed clove oil/ water.

Hi. Big plants! Good. I don’t know where live. But if it is summer as I presume if you transplant in a bigger pot the plants will be happy and healty for flowering starting end summer. With a transplant you will be better in control watering and avoid a rootbound. Yes I advise you transplant if you have possibility. And if you want make it don’t wait flowering. Make it soon.
Anyway you can also let plants in these containers without problem till harvest but you must pay more attention in watering/feeding as plants will grow more and more.
Good growing


I advise you some LST to avoid too much high plants .

Thank you Teddy. I am planning to transplant the ones that are in 5 gallon pots to 10 gallon pots. I’m in northern California and so right now is the middle of summer with 2 to 3 months to go roll harvest and plants 8 feet high so I’m a little worried about gargantuan plants that take over the earth.

LST? What’s that? If you mean did I top them, yes, more than once.
