So i’m a new grower and I started growing 4 plants and I have been doing great but I ran into a problem with 1 of my plants, i thinks a potassium deficiency, but i also have be turning my lights up slowly every couple of days during veg. So I just want some advice for what i should do or what it could be other than light or potassium!!

I’m about 5 1/2 weeks into the grow with my first plants and this pops up, just wondering what it is and what i can do to fix it? Hope i can get some help!

It could be a number of things. It’s hard to say anything for sure given a picture, as a lot of plant problem symptoms overlap each other. Without more information, I’d say it’s one of the mosaic virii, and possibly too much heat near the top of the plant, unless that’s an immobile lockout.
Looking like it’s locked out from accumulating nutrients. Need to flush and then resume light feeding program. A little more info on your feeding regime would be helpful. Cheers !!!

As a new grower my feeding regime is actually what i’m most confused about. I use Fox Farms soil and bottled nutrients trio, i have been watering once every week with the amount it says on the bottles per gallon. But as I know the FF soil has nutrients in it so i’m kinda confused how i should be feeding it.

Which Fox Farms soil are you using? Ocean Forest, Happy Frog?

I have them split right now 2 plants in Ocean forest and 2 in Happy frog

That’s probably at least part of the problem then if this plant is in FF OF as it is a hot mix and usually best not to start a plant in it.

Okay that makes sense, So i should flush the plants and slowly start back up a feeding schedule?

Happy Frog is better for smaller plants as Ocean Forest is much hotter with more nutes. Neither should need any feed for a while until the base nutes in them are used up. I use coco so will leave this for more experienced soil growers to answer. I know @toastyjakes uses them, perhaps he can help.

I’ve used ocean blend and added coco ; also gave water soluble nutrients on top of that. Some plants may have nutrient sensitivities but, most of what I was growing enjoyed the extra food. Just start low and look for changes in leaf if you need adjustments ( up / down on PPM ), should be just fine.
I came in hot on these 2 bubba but new leaf looks good and happy; I believe I was feeding around 200 ppm and is ocean blend with worm casting on top.

The soil should have all you need so I would go with plain water and skip the nutes until the plants show they need them. As for how long that will take, as I mentioned, better to get some advise from growers who know that soil better than I.

@DougDawson thank you very much!!

No worries. Lot’s of great soil growers that use those products here on OG so I am sure someone will be able to give you some good time lines as to when to start your nutes. When it comes to smaller plants I always find that less is more. The bigger they get, the more you can push them. But everyone has a different style. On a happy note, the plant does not look that bad and should be able to push through this for you with minimal effort. Best of luck.

@Beau do you use an RO system or tap water and use PH down/up?

Well the flushing advice was premature lol. Just water feed only until the plants use up most of the available nutrients in the soil. This will depend on length of veg and flower ect. But when you see older growth starting to lightly fade from green it’s time to start nutrients. @DougDawson Advice is solid !!! Look to growers that are doing well with similar applications. I’m sure your plants will rebound quickly. Cheers !!!

@BTYGMO really appreciate growers that are willing to help others succeed, i’m glad i found this forum to ask more questions! I’m currently in a class in college for Horticulture and Agriculture in cannabis and as I get farther in the class, growing cannabis can differ depending on the grower, which makes places like this very helpful! Thank you again

One more word of advice on water… RO water is extremely wasteful and there is better options that have zero waste. Look into the various Chlorine / Sediment filters like the Tall Boy or similar. Tap water is fine aswell if you are properly using it in your media. Some more diligent home work needs to be done here. Tap water can affect your microb life. Do some searching to see how similar gardeners handle the water. Lots of options but the little details mater… Wish I could be more specific but I’m a hydro guy with a bit of coco on the side for Fun lol… Cheers !!!

@JohnnyPotseed uses a Boogie Blue filter to clean up his water and says it works very well. It’s super simple and just hooks up to your garden hose. Personally I just use unfiltered tap water. I have an RO system but the waste is too much for me to use as a watering source. But there is no waste with a Boogie Blue filter.

I’d say tap water should be absolutely great to use with the “hot” soil for the time being 
It’s great to give info on microbial life in the soil. However, since OP said they’re new to growing I would suggest not to worry much about microbes in the soil. Plenty of other factors that will make a bigger impact on the outcome of this grow. Focusing on microbes seems to me like a “premature optimization” when someone is learning the basics.
Plant looks really good overall here @jakegrows710
Those spots on the larger leaves could be due to variegation (patterns / spots that can appear due to genetics - nothing to worry about).
The tips on the new growth look to me like they’re signaling that they’re getting too much light. You mentioned turning the lights up over the last few days. How strong is it? And how many hours of light per day?
