Hi guys, first time indoor grower here. Attached images have had me scratching my head for a few days already. Strange discoloration has been occuring on my first leaves and I can't seem to find any post with similar spotty patterns. The symptoms seem to be diminishing as new nodes sprout up, but I can still see some small spots of discoloration/lighter green.
Here's the current situation with my grow, as per forum rules:
1. Are you growing from seed or clones? Seeds, 2 northern lights from sensi seeds.
2. How old are your plants? 15 days from seed, a week and half from potting and first set of real leaves.
3. How tall are your plants? About 10cm including part of the stem which is below the soil, didn't want the seedlings to become too lanky.
4. What size containers are they planted in? Currently in a 2L pot.
5. What is your soil mix? It's Biobizz Light mix
6. How often do you water and what type of water do you use? I leave 2 to 3 days without water, meaning watering schedule is 3 to 4 days resulting is 2 waterings per week.
7. What is the pH of your water? Measured to 6.3.
8. What kind of fertilizer do you use and what is its NPK ratio? Whole biobizz lineup, currently using 4ml/l RootJuice, 2ml/l ActiVera, 2ml/l bioHeaven, 0.3ml/l CalMag, and up til now I've had to phDown around 0.5ph starting from 7ph rested mix. Water in my city is very soft, between 0.1 and 0.3 ms/cm. NPK with the nutes I'm using currently is probably minimal as I haven't started feeding bioGrow.
9. Do you foliar feed or spray your plants with anything? I have been foliar misting twice a day, in order to keep the humidity up, it has been quite low in occasion, currently sitting around 35-40%.
10. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights") Using MarsHydro FC3000 at around half power, ppfd app showing around 400-450ppfd.
11. How close are your lights to the plants? 45cm/17inches
12. What size is your grow space in square feet? 70x70x160cm or 27,5x27,5x63inch
13. What is the temperature and humidity in your grow space? Temps are also quite high but manageable from 26 to 29ºC (77 to 84F)
14. What is the pH of the soil? Could only read runoff, sits at 6.5.
15. Have you noticed any insect activity in your grow space? I initially thought it could be some kind of mite, but spots seems to be pretty stable and I believe appear even as the new leaves are opening, no expansion. Also checked under leaves thoroughly which wasnt hard as I was already seeing spots on the first 2 real leaves and didn't have to try to get my microscope inside a forest of leaves.
16. How much experience do you have growing? None.
A series of images:
A general view of the plant with some new leaves looking quite normal along with some older leaves with spottiness, including the worst offender (2nd node, secondary leaf on the right). Last image is the same plant in a younger stage, showing how the spots develop.
Plant next to this one is ahowing absolutely no spots, feeding the same, same light, same conditions. It's a bit smaller and took around 12 more hours to sprout.
I should also mention I have a fan blowing some but not directly hitting the leaves, resulting in a very mild plant vibration. Reasons I thought this could be happening are too much light, wind burn or perhaps some defficiency. I'm pretty stumped though, reason being the plant next to it is doing pretty good from a newb's visual standpoint. Also any wilting you may see is due to the photographs just been taken right after morning water.
Appreciate any help and thanks.
