Hi all,
been growing in RDWC for about a year, i got some gelato 33 going this time and today noticed something weird on a leaf so i cut and took a bunch of photos.

thank u , i checked all that out before posting. i cannot tell for the life of me if its a fungus or a deficiency. i didnt want to give the wrong treatment based on my newbie judgment. hence me posting it here for help .
but thank u for the link.
 
That happened to me once when I was flowering two different strains in the same RDWC system. One of the strains couldn't handle the high nutrient dosage I was giving the other. At the time I feared it could have been a root issue, luckily it wasn't and she pulled through just fine after toning down the nutrients. That damage never goes away tho. It's like a scar for the leaf.

U might be on to something here. I did notice some of the tips curling inwards which seems to be nitrogen toxicity, if this is true then my 780ppm nutrient level might be a little too hot for them. Since you noticed similar spots and fixed it by lowering your dose, i will be doing the same and see if this stops the issue.
Its my 1st time growing gelato 33 and looks like this is a very demanding strain ( previously i did mac and loui 13 and never had issues even when hitting 1200 ppm)
I did add a little bit of Epsom salt yesterday since the stems are purple . ill update here when i get some news.

Yea man. Some strains prefer a lower dosage but constant. Once the root mass is developed they consume nutrients very quickly. I have my plants in 20 gallon containers and the roots fill up the entire container. I noticed they eat 200-300PPM's per day, so as they eat, I replenish. It's some times best to do side runs on new strains to see their cap on nutrients and PH preference.
