Discoloration on the Leaves-Yellow tips and curling
GrislyOldVetstarted grow question 4y ago
I'm starting to see some discoloration on the Skywalker leaves. Tips are turning yellow and curling up a bit. Seem discolored on the interior of the leaves. Any thoughts on what the problem is and how to fix it would be appreciated

The canoeing leaves suggest light and or heat issues.
Hopefully your grow room has good circulation of air and heat is being vented out and new fresh air is brought in.
Some of the other leafs also look like they are having issues with some micro nutrients. Maybe this is being caused by a lock out from over feeding.
An EC of 2.0 is high for an auto. Need to cut that back asap.

Good Luck!

Hi there !
The dark green of the leaves (apart from yellow) may suggest a nitrogen toxicity. The yellow between veins could be sign of a lack of magnesium, brown spots and curling leaves says it’s been a long time lack.
Try to change your feeding with less N and more M.
I hope this can help, good luck 🍀

Nute burn in late flowerI've encountered some late stage nute burn and have brown and twisted tips on fan leaves as well as some bronzing. I am reading different treatment options for nute burn online but what else should I try at this late stage? I flushed ph'd water w/calmag and it's slowing a bit.

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

What are my leaves telling me?Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Something bad is going on with my Hulkberry plant. I think it might be due to giving it to much fertilizer.

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this

Help with burned leaf tipsThe tips of some of the leaves have begun to dry, curl, and look to be dying (see pics). I think it's some sort of nutrient burn, but I'm unsure. I water every other day w/ a solution of Miracle-Gro 24-8-16 at 50% recommended concentration. Used distilled H2O last 2 waterings.

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing.
I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"
