Leaf issues
CanaryGrowstarted grow question 4 years ago
Looking at the leaves, what you think is the issue with this plant? every single morning i have couple of totally yellow leaves at the bottom, edges are getting dark green and then dry. I flushed the plant but didnt see any improvement. I have 2 more plants that are doing great.

You either have pests, or two separate issues. The brown tips are likely nute burn or bad pH deficiencies. You already flushed, start reintroducing nutes. If it stops spreading, you're good. The brown tips that you already have are there to stay unfortunately, but it shouldn't hurt your end product.
Heat or light stress is also possible, but the least likely with your others thriving so much in my opinion. Of course different strains behave differently. Good luck, keep a close eye out for pests, and don't overwater.

The yellow leaf could be a deficiency, add some calmag into your mix for a few days to make sure it has every mineral it needs is available, check for thrips as they can cause deficiency as such and root gnats.
As for the leaf tips it looks like nutrient burn most likely but could be heat stress, i believe your giving it too much of something potentially your A n B or another additive such as BB.
hope this helps

Hello weed doctors, I need help identifying the problem and gathering advice how to enhance my second grow. It's only day 29 and my girls are sick, whI'm in biobizz lightmix. Started biogrow on D24, the dose was 50% in 400ml water. Until D24 only rootjuice. Yesterday gave 1400ml each, with 100% biogrow, pH6.4 EC 1.1. My water is hard pH7.7 EC0.8, so I wasn't adding calmag yet. There was 400ml runoff EC 1.9 - why? What do I do?

Pest attack. What can I use to eradicate?3 weeks of flowering, and the pests are still here. Can I play Beauveria Bassiana? Or just neem oil?
- The temperatures were very high here, exceeding 30°C, this week it will decrease.
- I have other plants to harvest and I'm going to take advantage and clean the grow.

S.O.S Droopy leaves on AutosJust watered these three plants yesterday. I had a weird feeling my ph Meter was not calibrated. I keep a secondary unhand to double test, but its batteries are dead. Could this be low PH? Other than that, Is it the intensity of the light I recently changed it to 100%.

Overfed P and KUnfortunately i have overfed PK as thought the bottle said 7ml per L but instead was 0.7ml. Noticed tips of leaves the next day browning so checked the feed chart again and pretty much shit myself. Flushed all 3 plants for about 5 mins and now they seem ok hopefully.

New growth is light green? (1st grow)New growth is light green – seems like Nitrogen deficiency or maybe light-burn? It's been getting slowly worse. Water ph is 6.7, Fox Farms nutes, AC Infinity 4x2 w/ 200w lights @ 18" on 80% power.

Nitrogen toxicity? Deficiency? Something else? Stumped!I don't get it. Is this N toxicity? Serrated upturned edges, clawing, slow growth. But how? FFHF 75% FFOF 25%. Just Cal-Mag water. No food. NLS in bottom 3rd of pot. Not wind burn. Not too hot/dry at all. N deficiency? Yellow leaves on first bottom two only. I'm stumped.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Deficiency or toxicity?Hello i'm not sure what's going on, is this toxicity or deficiency? She loojs happy overall but new leaves have weird color, curled down tips, some of em are yellow and some are brow - burned.. maybe it's because she's transforming into bloom phase, PH 6.2 but runoff is PH 7.1.
