What is causing this and can it be fixed? I was giving her some nutrients not a lot, and I haven’t given her any in about a week. Only water now and it started popping up after 4th feeding.

Looking droopy/yellow due to light burn?Looking like light burn (most intense from the top) and maybe overwatering?
I am trying Nectar for the Gods #4 soil for the first time, and I just put it in a grow bag and put the clones in it. Unsure if I was supposed to prep somehow beforehand.4y ago

Progressive yellowing on older fan leaves ~F14-F35Hi, past two weeks or so I've been noticing progressive chlorosis and eventually some necrosis starting from the edges of the leaves and working inwards.
Photos of this can be found in Week 18 Flower denoted by "For grow question #x 12/1"
Humidity low, could be related?

Cal/mag problem or heat issue?A few leaves have some problem spots popping up here in week 6 (see pics). No nutes, PH’d water. FFOF/HF/Perlite mix for medium under 20 hours of light. I’m guessing either got too hot from being in 90F heat for an hour or needs cal/mag? Any advice from any veterans out there?6y ago

Do these burnt edges look like heat stress or a nutrient issue?I noticed this browning on the edges of two fan leaves this morning. The affected leaves were right next to the space heater that runs all night (cold basement!), so I *think* it’s probably heat burn/stress. But don’t want to ignore a potentially more serious issue. Thanks!Week 5

Help! Why are my leaves turning yellow?Not sure why some of her leaves are yellowing on the edges.
Is this due to environment?
- 78.3°F | 64.8%RH
Or a watering issue?
- Currently she's drinking 8-9 cups a day through a sub-irrigated planter (EarthBox).
Or maybe a deficiency?
- See Logs for complete details.Week 10

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.2y ago
