White leaf tips
Mr_Weeds_Autosanswered grow question 5y ago
It actually is a little bit of both. The tips are slightly burned as you stated, but you can also see some leaf cupping which is a sign of light/heat stress. I would just back off of both a bit, take the light to about 24"-30" inches above the canopy and go a little lighter with the dosage of nutrients.

Young leaves' tips and edges slightly turning into yellow. Also there's some lime-green colouring in young leaf veins and single orange spot in an older fan leaf.
I'm not sure these are some kind of nutrient burn or because of cal-mag or any other micro deficiency. Any idea?Week 4

low pH problemsI discovered that I had irrigated with water at pH 3.5 for at least 5 days.
yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?6y ago

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"4y ago

Hongo mildiu?Hace unos días, las primeras hojas presentaron zonas con necrosis, y día a día avanzó. Será por el riego foliar con ? Por el viento directo del fan? O es un hongo mildiu? Un día la H.R llego al 80 90%, el crecimiento avanza pero muy lento, el sustrato parece tardar en secarse.4y ago

Nutrient burn or under watering?several leaves getting yellow at the tips. have not made any major changes to the environment in over 2 weeks. Water ph is 6.3. I am leaning towards under watering since the bigger of the 2 seems more affected. How would a more experienced grower proceed?Week 4

Brown tips and edges, but not on all plants.2 out of 3 Kratky plants are showing some crispy brown at the tips and edges.
Would I be seeing nute burn at 550-750 ppm? Why only 2 plants? Why only the Kratky but not the DWC? (Same strain.)
(I am actually using GH FloraDuo A and B)
Thank you!6y ago

Sick leaves, good budsSome leaves look sick. (Last photos at 8 weeks) Is this an overdose? Do I need to fix this? From fertilizers, I apply only ripen. I plan to give it 2-3 times and then flush and harvest.
I know that ripen helps to end life and makes the leaves turn yellow, but not so!5y ago

General concerns about the plant health and expectations from her.Will nute burn have a big affect on my final yield? Are my buds likely to increase much in size? Leaves discolouring normal at this stage? Does she look likely to produce just popcorn bud at this point? Can I do anything about it? Also not many leaves on the plant?6y ago
