I have not grown anything but hydro for some time now so before I put my foot in my mouth yet again I'm going to direct you to the above links on GWE and see what you come up with, by then you'll either have it figured out or another member who grows in your medium will have stepped in and helped to give you a more definitive answer. Happy Pharming!

10-14 day old auto flower showing some signs of distress (see photos)

plant symptoms

1. the original fan leaves and two others have some spots on them
2. two of the other larger leaves also have some spots and are curling down at the tips
3. the newest leaves that are coming in are closer to yellow than green.
4. the leaves that are curling down feel more dry than anything
5. plant is currently about 3.5 inches tall and 3.5 - 4 inches wide


I am growing it in a 1 gallon pot of coco coir (not transplanting)

20 hours of light 4 hours dark

Light: mars hydro TS-600. The top of the plant is about 28 inches away from the light.

temp/humidity. I have been keeping the temp at about 75 during the day and no lower than 68 at night. The humidity stays at about 40% so I had been using a plastic bottle on and off as a greenhouse to raise the humidity. I did see that doing so cause some water droplets to form on the leaves, not sure if that caused the spots on the leaves

watering with about 400 ml of 6.25 PH every 2 days or so.

Nutrients: I mixed in the recommended amount of 4-4-4 fertilizer in with the coco. I didn’t realize that I could have also mixed in the flowering fertilizer at the beginning as well so I top dressed the coco with the flowering fertilizer.

any ideas as to what is going on?

Ah, an auto. The strain sounds good!

[KronozOG]

I do plan on doing LST Heres a link to where I got the seeds sketchy website but i got the seeds quick. https://www.originalseedsstore.com/o...ien-auto~21708

In the beginning the seedling was stretching because the light was too far so I moved it from 25cm above to 15cm so closer to the plant and I had to put more soil in because of the stretching about almost two inches. A day or two ago I just moved the light back up because the plant grew an inch or two and getting close to the light. I don't know if the adding soil has to do with the node spacing.

[Puglover1]

What strain are you growing there? The early large fans leaves can do that, they get heavy. Plant looks like it has close/tight node spacing. Don't know if strain or light distance. Color looks good, healthy. You'll probably lose those big leaves in the future, do you plan on training it? Happy pharming!

[KronozOG]

Is it normal for the big leaf on the right to be curling down more than the others?

Remember, every plant is an individual.

Looks like calcium def from low pH like Rwise and Puglover1 said. I'll bet your run off pH is in the low 5's. Might need to flush till the pH is back in the 6's, then keep it there like 6.4-6.5

[danielelel10]

I'm giving them 16 on 8 off. And I have a big fan you can kinda seen it in the lighter picture, off on the right side. For the life of me, I'm giving these plants the exact same thing, but the closer smaller plant is getting worse again.

[Rwise]

Need to correct the PH on the closer plant.

[SoOrbudgal]

You keep saying 8-16 which is wrong, it's suppose to be 18 on 6 off with light for veg. 12/12 on-off to start the process of flowering. Do you have any sort of fan blowing lightly around these plants? Waves of light breeze strengthens branches to hold up the bud along with the right minerals. They needed longer lighted times if 6hrs was the only light time?

[danielelel10]

Should I start to make my plants flower?

I don't know how long I have had them, I fucked up a little already by not keeping track of time at all. But my bigger, lankier plant is about 55 cm tall(with some bends in the main branch, and I don't know how to tell if it is bloom time. My smaller plant is barely 35 cm, but she has had some damage already so her grow might of have been stunted. They are growing under a pretty strong light with a decent spectrum. It's a hy grow at a little more than half strength now, in a 8-16 light schedule. I was thinking I should load them up to full strength nutrients for a week or 2 and them prune, flush, start switching the light schedule to make them bloom, and then flush once more before switching to bloom nutrients (using "canna boost") depending on how quickly it starts blooming.
Honestly any kind of help or tips by people with more experience than me would be greatly appreciated.

Thank you!

[Puglover1]

maybe try for 6.3-6.5?

[danielelel10]

I'm trying to hit 6.0 every time, but maybe I'm not quite accurate enough. I'll recalibrate my equipment and hope it resolves itself.

danielelel10 Reads like a PH issue to me, hit the link at the top of this page "Plant Problems" and compare the pics to yours. What are you doing for PH?
