Seedling trouble shoot, leaf discoloration.

Mariosehr · Aug 22, 2018

Hi Everyone. New to the hobby.
900w ViparSpectra.
Feminized Amnesia discoloration to only one leaf closest to true leaves.
Week 3.Day1 from seed.
5 plants in 2x4, lights 18” from plants. No issues to other 4 plants.
Nutes Fox Farm trio.
Feed only once, half recommended. One day before week 3.

Why is this leaf discoloring, should I worry? How to remedy, rest of plant nice and green.

I’ve read to start counting week 1 once, you have a “plant” ? Can I call week 3, week one?

What kind of soil are you using and what's the Ph?

Is that 3 weeks from germinating seed?

Get the light at least 24" away. Read the instructions that came with it .

Lights currently 18” away. No other signs of discoloration on other 4 plants.

Back the light up to 24 inches. That peat is a pain in the ass and can become hydrophobic if not watered right.

It needs water. Water several times in steps a few minutes apart. Put it in a pan and let it wick plain water from the bottom until moist.

When using salt based nutes water until good run off and don't let the pit sit I'm nutrient water. Plain water won't hurt.

Hi Mario.

I personally have/had this exact light as well.
36 inches of distance between the plants this young, at full power wth this light isn't asking too much at all. Even 48 inches isn't much of a stretch.
In a 2x4 as well.....Optimal room according to the manufacturer is 3x3 from memory. (flower)
Personally i have my one in a 2x4 on half power, in a veg tent right now. But its too much for the plants.
Have to admit, i don't like my Viparspectra at all. Similar sympoms to your plants too.
Plants the same age, from the same seed, are in the flower tent loving life.

Id say start at 48 inches. If the nodes start to stretch too much, then lower the light a little.

Peace,

:peace:

I have them in a 1 gal. I water about twice a week. And spray/mist daily just enough to get top half inch moist.

Soil is moist. 1-5, 5 being drenched. I’d say a 3.
Bottom is a bit more moist.
