Looks like nutrient burn. She’s a little high in nitrogen. Water feed for a few days and convert to a bloom tea for the week.

Yellow and dropping leaves
What could be causing my yellowing and dropping leaves? It doesn't appear to be nutrient related and initial thought was light burn but not entirely sure. She's young and hoping I can get her to bounce back

Overfertilization? What could it be?
Hi guys I'm in the seventh week. What could it be? Out of 5 plants, of five different types, two plants have plagron substrate. The other three plants have a biocanna substrate and do not have this problem. Overfertilization?

Not Nutrient Burn
Well I'm stumped...ppm 600, pH 5.9...it certainly looks like nutrient burn but it can't be, tips yellow then darken and curl and get crispy. 3 days between pics in question and in diary. My only guess is that I upgraded from knockoff 100W LED to Mars Hydro 150W. Any ideas?

Losing colors :'(
I watered only 2L of water without nutrients this week (pot 30 L) You can see it on the diary photos, the plans have lost their colors (yellow). I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion Thanks !

What's causing my brown crispy leaves!?
Over the past week my plants have taken a turn for the worse. Many leaves went from yellowing to browning to completely crispy! Other leaves have brown spots on them and some of the stems are purple.

Around 60% of my lady has turned yellow. I'm almost certain it's not due to watering, and I've only given 1 half dose of nutes in the last week. Any ideas? Repost cus forgot to attach to diary

How do i fix this.The ph was way to high but i corrected it.My question is do i have to add more nitrogen to the feeding or will the plants go green again by themselves.How long does it take on average for yellowing plants to recover.

Leaves are turning yellow during flowering - is this an overwaring issue?
About 1,5 week into flowering the leaves have turned yellow, especially on the outside. The leaves in the middle are still oke, lower older leaves are dry. Could this be overwatering or something else? I gave around 1L/day, coming from around 0.5-0.7l/day the week before.

Is this Stating something or is it paranoya
I had a few leaves that were turning yellow, but they are lower leaves that are slightly yellowish on the outside, generally the plant has become a little lighter since it started flowering. Am I worrying too much? pictures were taken directly in the morning

Yellow tips
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore? A other reason could be light burn. But with a distance of 50cm I dont think so
