Crisdolemethstarted grow question 6y ago
What is this deficiency? seems like all my plants are going through the same thing. i top dressed dolomite because i think its a cal mag but since i am growing organic its probably better to make sure since it takes so long to break down. THANKS!👽

While the additional calcium won't hurt, it almost looks like a potassium deficiency to me. Maybe try some kelp meal too. Good luck and happy growing! 👊

Yeah looks like potassium deficiency. IF you wanna go organic, you can try a banana tea; great source of potassium

Dark purple areas on leaves — genes or environment/feeding problem?What the heck is this? Is it just purple genes or a stress/deficiency or a combination of multiple factors?
I have checked three visual cannabis plant health guides, and did not find a single issue which looks like this. Maybe a combination of 2 factors, but I'm not convinced 😐

What is causing this on the leaves? I'm not sure what I am doing wrong. Is it possible the heat and humidity are too high? Humidity up to 77% and can't seem to get her down sometimes. Heat is around 27/30 degrees during light hrs. Did I fuck up the transplant or grow conditions?

Foglie bruciate.Ciao ragazzi?spero vada tutto bene. Ho delle bruciature nelle foglie di una sola pianta, ho dato bio grow e top max biobizz. Umidità 50 % temperatura 27/30 °c purtroppo. Io penso sia dovuto alle luci troppo vicine, ma volevo un vostro parere. Grazie mille.

could this be due to the PH being too low?I watered 3 days ago with PH 6.3 Ruoff was 6.0
today watered with PH 6.6 runoff was 6.1
Can the brown spots come from the wrong PH ?

what would you recommend to do ?

Browning tips and lower leavesSome leaves have a little brown on the tips, and some lowest leaves are turning yellow then brown, although I have been looking it up and it seems to be normal? It's not nutrient burn as I haven't given any. Any clues on what it could be or if I should be concerned?

Curled leaves and brown spotsPlease help! My Acapulco Gold suddenly showed leaf symptoms today. Shouldnt be a lock out, I always water with drain and use lower doses than the BioBizz chart recommends. Used Molasses two days ago, could that be the cause? Its the only plant that shows this signs.
