Long battle with deficiencies.
Flashback25started grow question 5y ago
For a week i have been fighting deficiencies , the ph seems fine. Part of the problem was fixed by calmag but how it seems to be something else, maybe someone can help me identify.mid to top leaves affected. Also overall heat could be a problem (as temps outside rise)

Tend to agree with @DrCris here...looks like light issues...the "Praying" leaves would imply light is a bit too high for them and the fact you're seeing it in the upper levels would imply that. Don't forget too, damage done from any Ca/Mg issues where there are now yellow spots will not reverse, them cells are dead...Raise your light a bit and it should be grand.

Hey folks, I just noticed some kind faint yellow dots appearing on a couple of the oldest leaves on the Elixir. Any idea if its something to be concerned about? It's my first grow and I have no idea what it could be. Are they just old? Nutes? Disease? Temp? Humidity?

Potassium deficiency?Shes got about 2.5 weeks left, at first I thought the leaf discolouration was natural as harvest approaches but the necrosis has me worried. My guess is K deficiency. I was about to start flushing, will she make it to the finish line ok or should I attempt to fix this issue?

Leaves turning yellowLeaves are going pale and turning yellow all over the plant. Temp 25c, humidty 35-45 %. Bloom nutrients every second water. Two 150w lights over plant
Thought it might be over watering but only giving 400ml now every 2 days - 3 days and still seems to be progressing on the plan

Leaf tips yellowing. Overwatering? Or nute burn?I recently flushed my soil with water that was PH 7 (my soil was a bit too acidic). My question is: are the yellow tips and browning due to the overwatering from the flush? As well as stripping the soil of its calcium? Thinking of giving them 3-4 days before watering with calmag

Halb gelb, halb grünMy plant is currently showing slight potassium deficiency. But somehow only on one half of the plant. The other half looks well-fed. Can someone explain this to me? Like, why doesn't the deficiency affect the entire plant?

Leaf yellowingHi all.
In the last 48 hours there has been a few lower leaves which have lightened in colour to a yellow.
The whole leaf has changed at the same time so I’m not sure if this is an indication of an issue or if the leaves are being drained before the final ripening.
Thanks 😊

Hi, I'm sorry, I notice that this plant has a slightly yellowing top. I don't know if it's due to the slight burn it got about 2 weeks ago or a lack of micronutrients. I've been watching this for over a week and it hasn't gotten much worse. When I had a micronutrient deficiency...

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.
