hey DoDhLo, yeah i see those spots on the leaves. So basically you're overwatering this little seedling , this you can see from the puffy leaves especially the puffy space between the veins of the leaf. the overwatering is leading to PH fluctuations and the PH fluctuations are leading to those spots on the leaves. How to fix it ? simple : just follow a stricter wet/dry cycle and make sure you're watering with PH5.8 -PH6.... bonus question : what's the PH of rain water ? 5.5 ! hope this helps my friend ! 🚀

I think its awesome you're reusing your soil, too many of us growers chuck our soil with no thought about it. You should have some decomposing of old roots inside which is essentially compost...but i really think you should top dress with something...compost, peat moss, whatever dry nutrient mix you think is right and little till into the top few inches otherwise you may pop up with a variety of deficiencies or other things to deal with if you don't plan on fertilizing with bottled nutrients etc.

The picture doesnt look to have any spot. Anyway, the black bluish patches are a sympton of phosphorous (P) deficiency.

Second grow, second leaf issues. A quick google leads me to believe its phosphorous deficiency, that may be being made worse as its getting colder? Is it terminal or will she survive?

So- largest plant (photos above) yellowing lower fan leaves, overall light green colour on the entire plant. Possible Nitrogen deficiency? Otherwise she is healthy, budding up well and looks great. Any thoughts from the GD community? Thx as always!

DEFOLIATION: when should I do it? I start by removing some yellow leafs and I'm at 2 week from harvest. Should I remove the other biggest leaf, even if they didn't shadow the flower and are healthy and green? Also, what means if the stem is reddish?

I'm not sure what's going on, but the tips of several leaves are twisting over and/or turning white. I don't know if it's a nutrient deficiency, nutrient burn, I don't think it's too much heat, but maybe due to sun burn? I'm not finding much luck about white leave tips online.

Hi everybody! I noticed on the newer leaves those light green spots. Do you know what it is? Never happened to me before. Do I have to worry about some nutrient issue? Cheers.

My Tangie photoperiods small leaves are curling upwards around the edges. Anybody have a reason for this? It's the only one of the 4 exhibiting symptoms like this and only one of my autos of the 8 did the same thing. Is it too much or too little water? Not enough airflow?

Been struggling with leaf issues for weeks. Initially thought lockout due to N toxicity. Plants improved after flush in Week 7 but then promptly started worsening a few days ago. Is this a continuation of a lockout issue? Would you feed? Flush? Advice is welcome! 🙏

I was late watering one night last week and she was looking wilted, then 48 hours later, she looked this like with all fan leaves wilted or dead and crispy and she isn't standing back up after watering. Nute-lockout? Underwatering damage? I always check nute pH. Thoughts?

Hi, After I topped, the new growth tips started growing vigorously, but the leaves are weird. They have a loose&floppy appearance, the serrations on the edges are very wide and one of the leaflet didn't even grow 1/5th of the size of the others.. Do you know what it is? thanks!
