Ah, so ya got brown spots on yer cannabis leaves, huh? Now, during the flowering stage, them brown spots sure can give a grower like you a bit of a scare. Don’t worry, though. We’ll go through all the causes step by step, just like how I’d walk ya through making the best homemade jam. Simple words, easy steps, and by the end, you’ll have yer plants lookin’ healthier than ever.
1. Brown Spots from Nutrient Issues
Now, most folks don’t realize it, but them brown spots might be from not givin’ enough nutrients. You see, plants need calcium, magnesium, and a good mix of them other nutrients to keep growin’ strong, especially during flowering. If they miss out, them leaves might start showin’ spots. Calcium, in particular, is important – helps build them strong leaves and keep diseases away. Magnesium, too, plays a role, keepin’ leaves green as the fields in spring. Without it, ya might see yellowin’ around them brown spots. Make sure yer fertilizer got all them nutrients to keep yer plants happy.
2. The Trouble of Low pH Levels
Now, yer soil or water might have a low pH, especially if it drops below 6.0. That’s a no-go for cannabis; they’re a bit picky, y’know? They need that pH balanced just right, like a good soup broth. When it’s too low, yer plant can’t take up nutrients proper, and you’ll see them brown spots start showin’ up. Get yerself a pH tester – it don’t cost much – and check yer soil or waterin’ mix. Make sure to adjust it back up if it’s too low, maybe with a bit of lime or other balancing stuff they sell at the garden store.
3. Watch Out for Rust Fungus
Some folks don’t know, but them brown or yellow spots might not be from nutrients or pH at all. Sometimes it’s a case of rust fungus. This sneaky fungus gets on leaves and makes ‘em look like they got rust on ‘em, just like an old gate left out in the rain. It’s a tiny parasite, and once it settles in, it spreads fast. Yer best bet is to prune off the affected leaves quick as you see it, don’t let it spread. You might also wanna use a gentle organic fungicide safe for cannabis, but be careful – don’t use too much durin’ flowering.
4. Overwatering or Underwatering
Now, sometimes the problem’s just plain ol’ waterin’. Too much water, and yer roots get waterlogged, they rot, and yer plant starts to suffer. Too little water, though, and yer plant gets thirsty, starvin’ for nutrients, and ya get them brown spots again. Try to find that sweet spot, not too much, not too little – kinda like makin’ tea. Let the soil dry out a bit between waterin’ but not to the point it’s all dry dust. That way, them roots get a good drink without drownin’.
5. Pests and Tiny Munchers
Now, brown spots could also come from little critters nibblin’ away. Things like spider mites and aphids love munchin’ on cannabis leaves, and they can leave behind brown spots like little battle scars. Check the underside of the leaves – if ya see little spots movin’, that’s them mites. They’re small but can do a lotta damage. Use a natural insecticide or neem oil spray, but be gentle durin’ flowering. Just a light spritz can keep them bugs away without hurtin’ yer buds.
6. Keep a Steady Check on Yer Plants
Last but not least, just like how ya keep checkin’ on a pot roast to see it don’t burn, ya gotta keep an eye on yer plants, especially durin’ flowering. Look out for any signs of stress – brown spots, yellowin’, or wiltin’. Catchin’ these early can make a big difference. Regular checkups can help you spot them brown spots before they take over the whole plant.
Alright, so there ya go – a bunch of reasons why ya might be seein’ them brown spots and what to do ‘bout it. Just remember, like tendin’ a good garden, takin’ care of cannabis plants takes patience, some good ol’ checkin’ in, and a bit of know-how. Fix up the pH, make sure nutrients are all there, watch that waterin’, and yer plants will be bloomin’ all happy-like in no time!
