Yellowing, burnt tips and edgesHello fellow growers I noticed this happening rapidly after I top dressed. What kind of deficiency is this? Is this nutrient burn as well as a deficiency? Solely a Ph problem?. So far I’ve come up with maybe potassium deficiency and improper Ph when watering? Please helpLeaves. Edges burnt

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

New leaves burned tipHi everyone! I need some help figuring out what's wrong with this plant here in the photo.
New leaves are getting their tip burnt so I guess it's overfeeding but I'm not sure, I'm using the minimal amount of pk 13 14 Bionova, Calmag Biobizz and Nirvana,
Should i flush them? TxWeek 8

Defoliation late in flower on Auto'sI like to defoilate, If I were to pick majority of the fan leaves off of these plants being Auto's, will they react or stress too much? I like to defoil near the end of flower to really push all the focus to the budsites. Happy Growing!2y ago

Leaf discolouration. Nutrient deficiency?Leaves are discoloured and clawed. Started about a week ago with yellowing of tips and clawing at top of the plants. Now lots of leaves are slowly changing colour. Thought it was nitrogen toxicity but my runoff is 330ppm. Are they deficient in nutrients?5y ago

Yellow tipsI noticed the tips of the leaves starting to yellow, mainly on the new growth.I haven’t noticed any other issues, being my first grow maybe I’m overlooking something. I raised my light up to 26-27 inches from 18 to see if that helps. Could this issue be from something else?Week 5

Dealing with Nutrient Burn and Salt Build-UpI've observed salt build-up and nutrient burn in my plants recently. I've taken action by flushing and removing 60% of the affected leaves. Now, I'm considering whether to remove the remaining affected leaves and when to proceed with top dressing. Please advise.Week 6

What deficiency could it have?I gave a total of 700 ml in two separate days, using a solution made by boiling 6 eggshells (180–220 ppm), first time pH 7, second time pH 8. The plant is 19 days old in Lightmix Biobizz, @sf1000d 16h/day, never fertilized before. Could it be Ca deficiency or something else?Leaves. Tips - Burnt

Flush or what to do ?Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?3y ago

Yellow leavesHi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?6y ago
