it's soil pH, fix it with beneficial bacteria or humic acid. Hope this helps ! 🚀

Mm the leaves are looking rather sick :/ but brown decaying spots can be water spots where existing leaves prevent other to get enough air. The leaf veins are pretty dark, if its a nutrient lock out then your ph is out, a real solid flush can help. Id stay away from nutes for the next wee while. Good luck mate! Il look up some proper info for you

This does look like a problem with ph, it looks like it's got so bad that it's causing a lockout. You need to check the ph FAST!

My plant has spots on the leaves as well as yellowing starting from the tips. It recently received clear water for a week. Otherwise, the plant is doing well. Any ideas regarding these spots? In the meantime, thank you in advance for your responses.

I have no idea what these brown spots are on my seedling?Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.

Help! Lower fan leaves drying out slowly at the tips and edges. Doesn't look like nitrogen deficiency to me, but please prove me wrong!10 days ago the lower set of leaves started drying out (they get brown not yellow). They don't receive light, but now it's already started showing on the third set of leaves. Does it look like nitrogen deficiency or can it be something else? Just gave it full strength nutes.

So closing week 7 now and my 4AM are showing signs of deficiencies again. I watered(with nutes) ph'd around 7 past few times and the runoff has still been ~5.9, indicating acidic soil(nute lockout)?At this point, you think it's best I just flush with plain tap water(ph ~7.7)?Week 6
