What is this brown spot?
What is this brown spot? 18” from light. Just fed about 10 hours ago with dr.Earth 1-1-1 liquid solution watered in with 1/4 gallon of water. It is the only spot on whole plant. I know the temps are high. Wondering if it could be something else.

Look like Zinc and Calcium deficiency? Watering with 5.8/5.9pH, 2.06 EC (Runoff 5.8pH, 0.78 EC) Few leaves had small nutrient burn on the tips earlier this week. Nutrient burn appears to have tapered off.

Deficiency?
Anyone seen leaf damage like this before? 6 weeks into veg in FFOF. A few fungus gnats but no real infestation. Not adding any nutes yet. Really concerned as the plant is looking less green and more yellowy than it did last week.

Many or low nutrients?
Hello Growers What could it be? I thought it would be a nutrient deficiency (EC-1.0) so I picked up the nutrients to EC-1.4, but it's getting worse. Do you think they'd have a lot of nutrients?

What is this brown intrusion upon my plant? And how do I obliterate it?
Another question?! Anyway, what the hell is this browning? I think it's light burn. But why is it lower too? PH? Magnesium? Nitrogen toxicity? Par: 1300 PPFD Fox Farm tiger bloom 7 ml/gal. Fish Shit 3 ml/gal. See diary for environmental conditions. Thanks for the help. Again.

Deficiency?? Excess? Neither?
Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice 💯🙏🏼

Only single leaf, still cal/mag?
Anyone knows what causes a single leaf to show rust patterns, almost like cal/mag deficiency. Whole plant looks healthy except for this one leaf, literally. DWC, and I use tap water

Brown Edges on Leaf. Bit of yellow and purple.
What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

Overfed P and K
Unfortunately i have overfed PK as thought the bottle said 7ml per L but instead was 0.7ml. Noticed tips of leaves the next day browning so checked the feed chart again and pretty much shit myself. Flushed all 3 plants for about 5 mins and now they seem ok hopefully.

Browning leaves
My leaves are showing some brown spots 5 days post transplant. I also increased my light from 30% intensity to 80% intensity. I have them 18” away currently. Am I showing signs of light burn? I have since turned the light back down to 50% and I am not on a 18/6 cycle
