answered grow question 4y ago
Personally I would say nutrient lockout rather than one specific issue, check the run off ppm and Ph and adjust accordingly then feed at half strength. PK and calmag are both notorious for causing lockout in the medium

Possible toxicity or deficiency?
I saw this on one of my bottom leaves this morning. Hopefully someone can give insight of what it might be. I'm concerned that it is phosphorous deficiency. I didn't notice it a day ago, but I wasn't looking closely. 2 days ago I watered her (540 mL, 1/4 tsp nutrients). Thoughts?

bottom leaves yellow
Helloo So today I've noticed that the bottom leaves are yellow. I don't really think it is a problem since I think the reason is that they don't get enough light because are covered by the bigger leaves on top. But it's better to ask since I'm a newbie. What do you think?

Hi. What is it missing? Is it a lack of potassium and phosphorus? or rather due to weather or old age. This is an older leaf from the middle part of the plant

What do these yellow markings on the leave tips mean?
What do these yellow tips on the leaves mean? Are my lights to close? Looks like light burn to me and have adjusted the lights up 10cm for now. Still wanted to make sure since I thought they need more lights during flower. Thanks heaps

Yesterday i see new yellow leaves (plant 2). I have just checked them again and on the second plant the two small leaves are now brownish. What could that be? I water every two days and the soil is not wet but slightly moist. The other plant 1 grows wonderfully.
