Phosphor? wind Burn? my Leaves crisp up!
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!

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.

What is that?Yesterday evening feed 0.5 litre EC 1400 pH 5.9. Runoff was EC 900 pH5.6
Increased light intensity to PPFD 600.
This morning larger upper leaves are in "praying" position, one leaf closer to bottom looks sick.
If it's a light burn, why not on upper leaves?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

What is she telling me?Anyone know what she’s going through? Four weeks old, using tap water with hydroguard and GH FloraTrio nutrients. PH seems to go up from around 5.6 to 6.1 in a matter of hours. Ppm=635 EC=1.2 right now. Been going very easy on nutes, about half strength still. Could that be it?
