My soil and run off are coming in between 6.0 to 6.2, I'm running a low budget grow atm as its my 2nd go, my 1st came out nice but very low yield as it was my learn and trail grow, my setup atm is a 4x4x6 with 1 1000w amazon led ( buying a 2nd in couple weeks) hanging about 18-24" above the canopy, I'm using coco with perlite medium in 2 gal plastic pots (transplanting in 5gal fabric pots in about 2 weeks), I'm may wait a day or 2 and see how it looks and hopefully she'll bounce back
@troydolton1989 I definitely understand working within a budget and learning as we grow.
Concentrate on pH and not over/under watering.
More importantly that the light height is the intensity and the heat it’s subjecting the plant to. You can download a free app to ck PPFD. It’s debatable but in veg 250-600 is the range most often cited. Try to balance your leaf temp between 75-85F and your PPFD high enough to give a daily light integral to 30-45 while ensuring you have a change of air per min to provide CO2. This will optimize photosynthesis.
Then maintain humidity to a vapor pressure differential at your room temp to .8-1.2 kPa. This will optimize transpiration. (Look up a vapor pressure differential chart to get the optimal humidity for your temp).
Once those are set, respiration will take care of itself by burning the carbs created in photosynthesis.
The brand of nutrition you provide is less important than the qty. don’t over or under dose based on the pace of photosynthesis and transpiration. We’re pushing these plants. Just don’t push them off the cliff.
I agree it looks like manganese but being a mobile deficiency I’d expect to see it on lower leaves first.
All too often I see growers detect a nutrient deficiency and want to provide it the nutrient that is lacking without addressing the cause of the deficiency. Before attempting to diagnose any nutrient deficiency, test the pH of your water, as it can vary widely depending on the source. It should be between 6.0-7.0. Then, check the pH of your soil or other grow medium.
Soil: 5.8-6.8
Hydroponics: 5.5-6.5; most hydroponic nutrient brands will indicate an ideal level for their product
If the pH is correct, your plants may have a nutrient deficiency.
I recommend top dressing organic nutrients. This will grow a healthy plant without having to flush synthetic nutrients, salt build up, pH issues, etc. Save all that for later.
Your Hydroponics pH should be 5.5-6.5. What is yours?
while nutrition is important and growers tend to focus there, it is not the only primary concern. Nutrients are like vitamins to us. Plants feed on light. high Light intensity increases photosynthesis. Increased photosynthesis increase growth which increase nutrient (vitamin) requirements. Balance the light, air recirculation, temp, humidity, and hydration to promote healthy growth and provide nutrients at a level to sustain the process.

@mh47pcncoic what is the best way to fix this if that is the issue, its the only 1 out of 6 that looks like it, I'm going in coco using biobizz nutes, I'm mixing 1ml to 1l of veg mix, 1ml to 1l of silica, 0.3ml to 10l root excelurator and pH'ed to 5.8-5.9

I'm wondering if it would be best to swap from my biobizz nutes to the H&G aqua flakes?

Sorry auto correct deficiency
