Seedlerstarted grow question 3 years ago
Hey, i have a problem where 1-2 plants got some issues with brown-bronze'ish spots on the lower leaves.
i have some photo to show you. also i'm worried it might be thrips but i don't really see any bugs.
it also might be wind burn because the fan was a bit harsh :/
any idea?

I would double check the pH. Could also maybe be low on calcium. But make sure your ph is good, because that can have a dramatic impact on nutrient availability. Or maybe even if you can add some humic or fulvic acid? Humates can improve nutrient uptake. The splotchy pale green almost looks like an early onset of potassium deficiency. But being on the new leaves, I’m not sure if that’s right, could actually be magnesium. Maybe just a little extra CalMag. Calcium without any magnesium can potentially start a magnesium deficiency. Maybe even some CalMag with a little Epsom Salt (Magnesium Sulfate) could make a big difference…
I am still learning too. :)
Best of luck

The start of mag Deficiency, or watering the leaves.

Need to see more! Can be nutrient burn, overwatering, deficiency, or Ph—- or a combination of any!

Root rot or pH imbalance?This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Burn? Deficiency? Hydroponic fgrowproblems in DWC. I am using TA nutrients (Lucas formula). Running EC 1.8 and pH 5.8. One of my plants look good but the other plant shows lots of problems. RH is 55%, Temp 25-26C. PPFS is 450μmol/m²/s on average. Any idea how to fix it? Dilute the nutrients? Ideas welcome

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.

Thoughts on leaf symptoms? The other plant in tent is doing same thing,but plant in other tent getting similar feed not. see diaries for more picturesK deficiency? Hard to believe that can happen in 65-gallon pots.Are getting big though.New growth tips looked yellow,hit them with water-soluble K and the new growth edges seemed get green.Some toco-ing, humidity is kinda high. Too intense light(800 ppfd), not enough C02 maybe?
