Hi mate, looks like your plant may need a feed. She will start to kill off less important older growth. RAISe her EC a little and see if this helps. Good luck and happy growing

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.

Calmag excess or defiency??
So.. I have 4 flowering plants. I feed them the same stuff. Same quantity. 2 out of 4 showed some signs on the older eaves and i was wondering if its an excess or a defiency. Yellow with brown spots. Not a wind damage for sure.

Brown Edges on Leaf. Bit of yellow and purple.
What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

K deficiency? Or something else?
Not sure how to go about this deficiency. PH is solid at 6.5 so it’s not a ph issue. It seemed I had corrected the deficiency when it first appeared a few weeks ago, but now the brown spots seem to be spreading again. I think it might be K but not sure? Any ideas?

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)?

Is 8 oz of water about right for 3 weeks old plants? Also thinking about LST, is it a good time to start that now? Also is buying nutrients worth it when it comes to harvest? Or is it more dependents on the power of the light ? Thank you for any advice 💯🙏🏼

Sudden brown on leaves

Is this turning purple from temp change
So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks

Why are my leaves getting brown yellow?
My leaves are getting brown/yellow, I saw online that it's a bad sign but I don't understand if it's under watering, overfeeding, underfeeding, light burn ecc? Thank you so much for the help first time grower.
