I am getting very sad... One is saying Ca deficit , one Mg deficit, one N toxicity...what should I do? I am really confused now... As I said, the dots are on more then 70% of the leaves. On this amount if there are indeed spider mite or any other bugs, I would have seen them for sure. As I said, I have gnats, but not a huge amount and they are not feeding on the leaves

what should I do? flush, not flush, give Ca not give Ca, too much nutrients? too small amount of nutrients? should I give more, should I give less? everyone is saying different things... :(

one more thing to add. last time I watered her was last Monday. The soil is not dry yet. Usually she was drinking the water in about 5 days and the soil was dry on top. So ...is there a rot blockage there maybe? PLEASE ADVICE

PH is probably off causing lock-out of MG/CA (or whatever) or toxicity of N (or whatever), as they say if you have any problems in soil/hydro fix your PH FIRST. Run PHed water through there on this next flush, check the runoff (so if you run 6.5 through and get 7.5, that is bad, if you get 5.5 that is bad) - there are directions around and you can be the judge on what your soil Ph should be looks like around 6.5 anything below that you lock out P,CA,MG in soil - seems the problem to me. https://www.rollitup.org/marijuana-plant-problems/133385-ph-lockout-guide.html

  • Both of these leaves in figure 3 and figure 4 are from the same plant. It could be over fertilization, but more likely it is due to the pH being off. Too high or too low a pH can lock up nutrients in the form of undisolvable salts and compounds, some of which are actually toxic to the plants. What then happens is the grower then tries to supplement the plants diet by adding more fertilizers, throwing off the pH even more and locking up even more nutrients. This type of problem is seen more often in soil mixes, where inconsistent mixing of the medium's components leads to "hot" spots."​

very nice plant and very well done with the bq soil. never thought of using there brand for soil. especially as i live next to one of the super stores......but the spots. umm i know youve covered the bug thing. but they do look like bug bites. all seem to be on youre veins and main vein and i can not think of anything else that could cause this type of damage. 10 mins im just going to check this book i have. it all about pest attacks on plants and how to find them. as sometimes even with a mg they can be hard to find

the B&Q soil was my only option. I live in a country/city where for gardening I have only this store.

The PH is a bit high now...to be honest it was always near this values. It's between 7 and 7.5

ye agreed. but dont "hot spots" accour between the veins not on them.


ive looked up this damage the best i an and keep coming back to thrips and them gnats or aphids doing this damage my friend. try some neem oil..nothing to lose. if it starts to stop once applied then great. if it was summer a ladybug would deal with this for you. im sorry but ive never seen a ph issue nute lock out ect ect do this type of damage. im not the most exp far from it and i might be sticking my neck out here but would hate to that plant get eat alive. if im wrong i do appolagise

Keep looking for mites, some of them can be very hard too see even with a magnifier. Those spots are caused by insects, not nutrient issuses...

If you follow runpff pH you will only become lost and end up very frustrated. Runoff pH means just about zip...

Spider mites would be visible to the naked eye. The N toxicity I suggested came from Jorge Cervantes Bible...but what does he know anyway?

You offer advice yet add peat moss too your mix to add drainage. Then ask the basic question will adding sand help drainage. Jorge didnt teach you how to use these amendments properly?

And perkle keep looking for bugs, especially mites. white dots such as yours are caused by mites or thrips. thrips usually leave more of a little trail than dot.. look into neem as mentioned and other ways to control them....

After many discussions with the guys on the forum and many forums checked and guides...I think I will stick with a flush Monday and after I'll give some Ca solution + Mg(epson salts) and some nutrients and hope for the best. The leaves I will not regain, that's for sure, now I hope I'll pull it through another 3-4-5 weeks until the buds will be done. If not...would be a sad but at least I've learned many things on how to grow cannabis.

Thank you all for the replies, advices and links, much appreciated.

You are most welcomed kind Sir. I regret the 'ugliness' that occured and I wish you and yours the best harvest ever.

I'm not thread jacking, but I have these "spots" on my leaves as well. I am growing two plants right next to each other. Only one plant seems to have the spots. I have checked for mites and bugs and found none. This started probably 2 weeks ago, and has slowly gotten worse. I am only a week into flowering and fearing that it may get worse and I could end up losing plant. There isn't a bunch of spots on the leaves, probably scattered along them and the leaves are a healthy green color other than the little red spots.

Please take some clear pics of your leaves and give some more details regarding what type of soil are you using , what nutrients and the frequency, lights etc and we'll take it from there and we'll try to make something constructive. Thanks for writing on this thread
