wrinkled leaves mean too much nutes.

  • Strain; NORTHERN LIGHTS FEM (ILGM)

  • Soil now, started in coco?

  • System type? ??

  • pH - have only used distilled water. Have made some water pH 6.

  • What is strength of nutrient mix? I have only added nutrients once. Seasol.

  • Indoor

  • Lights: 250W HPS.
    Tent: Jungle Grow Room 1x1x2m

  • Temps; Day: 21.5 degrees C
    Night 15 degrees C

  • Humidity; Day, Night 50-60

  • Ventilation system; Yes. Fan.
    Cooling tube for light.

  • AC: No

  • Co2; No

I’ve only given nutrients once at 4 weeks. Perhaps it was too much?
I read after no nutes at early stage.

I had sprayed water on plant (until I noticed yellow marks).

The yellow marks have only appeared on the middle of two fan leaves.

Many thanks for your advice :slight_smile:

How long would it take to show up in the leaves if I’ve overdone the nutes?
I have only added nutes once and that was before I read not to!
Learning heaps as I go.
What to do and what not to do!

Im with @Countryboyjvd1971 on this. Looks like a mark left, possibly, by a liquid. Id keep an eye on them for now. Other wise she looks healthy. She looks old enough and big enough to give nutes, Just don’t over feed.

@TassieDevil

Over doing the Nutrients will show up over night. Just cut back to 50% for now and just skip the next feeding and just go with water for the next two times. Then only 50%. By the way what did you use for soil ? That’s most likely where the problem is… I’ll bet it’s high in N P K


#8

@TassieDevil…bad overdose a few hours. Mild overdose 8 hrs

It’s a learning process…to learn to read the plants and giving them what they need to be healthy.


#9

wanna bet a dollar on “Miracle No”? :wink:


#10

Well I was thinking that your soil was to hot for your seedings…


#11

I used a soil for cacti and seed raising.


#12

At least you didn’t say Miracle Gro :slight_smile: Not trying to be mean. A lot of people find this forum (me included) when they have their first growing problem. and more often than not, sticking the seed in Miracle Gro was the beginning of the problems.


#13

I’ll read more about it!
My next grow will be more calculated from what I learn here and by just growing.
It’s awesome just to look at how she grows. I topped her last week and she’s doing well.
I actually felt bad cutting her!


#14

I too am growing NL and I have similar spots only rust colored. After ALOT of reading I found out it was rust fungus or a cal/mag deficancy.


#15

cut the leaf off .
