Unknown yellow spots on lower leaves?
GMSgrowsanswered grow question 4 years ago
Older leaves do whither and die. They will help supply other parts of your plant with nutrition. It sucks the life out of them so that other leaves may thrive. Be careful on using full strength nutes. Over feeding is very detrimental to your plants and if they do get overfed your nuggies and overall harvest will suffer. If your following the fert label for feeding, just go half. Cheers

Yellow spots on bottom leaves.Starting to notice big brown/yellow spots on the bottom leaves only. Plants look healthy at the top but not happy(not praying and look droopy). I water every 3/4 days so it’s not a matter of being locked and Calmag is also used. Can’t figure out what the problem is here.Leaves. Curl down

Yellow/gold spots on top fan leaves in bloom phaseI noticed a couple of the top fan leaves have got some small yellow/gold spots developing. I've been using the same Bloom feed for this plant as my 3 Bears Smile which is 8 days further along. I'm wondering if that might be causing the problem and how I fix it.Week 9

EC too high and leaf yellowEC 1.45 and some yellow leaf… I adjusted the soup by adding water to it and the new leaves seem to be pretty ok. Otherwise, all other parameters are good. It’s odd bc I followed instructions of the brand (Platinium Hydroponics) and the EC lvl is still kinda high. Suggestions?Leaves. Color - Yellow
