Brown stains on leaves edges
blasterw32started grow question 6y ago
The top leaves on my GG#4 started to get brown on the edges. Initially I thought it was light burn, but the stains kept progressing after I readjusted the light distance. Is it a nut burn?

I don't think they're burned. Leaves burned by light behave differently. They twist and look dry. Your leaves look good, try to raise the PH a little to 6.5 if you are watering with a smaller value, or check the EC and play with the dosage of nutrients.

Which pests do this?Exactly what pest does this kinda damage? I have my guess, but wanna get other growers' opinion on this type of yellowing of leaves and brown spots. 6 weeks into veg. It started very early on at bottom leaves, once I trimmed them this brown spots appeared on top growth.

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?Week 7

Spotting issue consistent in all my grows. Have always thought Cal deficient but more Cal never fixes the issue. PH always checked with 2 PH pens 6.2-6.8.Always pops up around the same time in flower.. week 4/5. Brown irregular spots and occasional curling down on the fan leaves. The only things I have consistently used in all the grows is the LED light, RO water, and CALiMAGic. Switched to dry organics but now its back. N toxic?
