Light intensity or cal/mag def?
ReeLeafstarted grow question 4 years ago
Light intensity or cal/mag def? Something third? I raised the light a tad and fed a teaspoon of Epsom salt to the res, plus gave it some adjusted and fertilized water with more calcium than it's used to. It's only one leaf for now, I just want to make sure it doesn't spread.

The location is definitely strange but it is led light burn. I have had similar issues when the humidity is too high and water droplets build up on the leaves from transpiration. If the leaf is getting too much wind from the fan or intake then it can combine with the led intensity and burn them also. But in hydro it is common to lose a leaf here and there. Nothing to worry about at this point. Just keep an eye on the plant for other leaves starting to get damaged. Good luck flowering her!

hi mate, I've been looking at your diary. it doesn't seem to me to be a burn of light, in the photos you can see some leaves with dry tips that are not with spots that show in the photo. it may be lack of magnesium or calcium but due to the color of the bright green leaf and the appearance of the spots it seems to me to be lack of calcium. wishing you good luck 🙏🌱🍀

@Mrs_Larimar,
It's actually not an upper leaf, but granted if it was so.. And it's the only one affected I can find and it's mid-bush. So it's a bit of a mystery really. Because it looks like light burn indeed, but in the wrong place to be light burn. I figure it could be scars or akin from old light burn perhaps tho, from when it was centered more.
@Animatey
It's about mid-plant, on the side. It has been getting water with very little calcium in it, so cal is also a possibility I figure.

Is it on a lower leaf? Mg is a mobile element so you'll notice the deficiency in lower leaves first.
Mg def shows up as yellowing in the veins. That could be what's going on with your leaf, but the purple lighting makes i difficult to say.

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

Dry leaves / dying.Why is the leaves of the one "cola" drying like this? Looks really unhealthy, at first i panicked that it must be mold or something like that i have never tried before. But the bud seems fine. Is it under watering as i forgot to water for almost 72 hours? And if so, why only one.

Nutrient lock out hot soil question - stunting starts on 3rd set of leaves always?I noticed that they always deteriorate when the third set of leaves are forming. If these are in fact stunted from the nutrient lock out due to hot soil, does it make sense that growth is vigorous until the 3rd set of leaves form?Week 2

DefoliationThis is my first auto grow, I usually train and defoliate my photoperiodic plants. I thought just lst will be fine for my first autos. I have 3 bushy plants in my 80x80cm tent and the space is limited. I’m wondering if I can still defoliate them in week 4 of flowering.
