Leaves discolored not sure what to do.

[geemonty]

I am new to growing. Have only grown 3 plants to harvest. Leaf tips are browning as well as a light green variegation is showing up on leaves. A few leaves are even curling a bit.

Growing in soil. 3 parts miracle gro potting mix to 1 part peat moss. I amend the soil with 3-4-4 Garden Tone and 5-1-1 Alaska Fish Fertilizer. I water every other day with well water and once a week mix in a glug of the 5-1-1 fish fert. My light is a Viparspectra xs1500 at 100% hanging at ~14" above canopy in a 2'x2' space. I have successfully grown this way and received good yields 3 times so far without any issues until now, beginners luck maybe. The only thing I changed this time is that I previously grew from seed whereas this grow I started from a super silver haze x apple juice clone. The plant looked amazing just 5 days ago. Not sure what to do. I couldn't seem to get the camera on my phone to focus, hope these are clear enough.

Any help would be appreciated. I was just going to flip it to flower when I saw this appearing and decided to wait to hopefully correct the issue.

no pro, but i think you have some nutrient burn/ too much nitrogen, and what is the PH at?

I use GH ph test concentrate so I cant give you a super precise number unfortunately. The runoff is at ~5.5 my tap water I use is at ~7.

for soil, i think ur run off might be a little too low, soil likes 5.8-6.5, but OCEAN FOREST should stabilize.

i say 5.8-6.3 because my DUTCH PRO soil nutrients says that,
either way

I haven't even had to worry about the ph until now I wonder if this strain just consumes less nutrients or something as I have done everything the same.

I have garden lime I use outside in my garden, would this be OK to use with cannabis? Or should I just do a flush and back off the nutrients for like a week?

Regardless of steps taken, I assume I should hold off on flipping to 12/12 for like a week until this is resolved

Usually dont have to in Soil.

i would not do anything just yet besides giving it just water, let some others chime in and also id wait on flipping till you figure out the issue.

studying deficiency charts.

miracle grow has slow release nutrients which screws your plant up. i see all sort of problems and deficiencies.

I thought i make a list on how to ask questions for new members when they join THCfarmer. This should help members to diagnose problems without needing to ask multiple times throw out the day to different new member. lol! Please allow this thread to have the ability to be updated constantly. as...

for starters, your curled leaves are either, your temps are too high and low humidity or to much light.
What stage is the plant in?

1. look up cannabis VPD charts, you want to match those numbers as much as possible

2. Humidity probably too low goes into 1.

3. i don’t know what all is in that miracle grow slow release bullshit

4. 5.5 ph run off for soil seems too low, should be around 6

5. Can you test the PPM of the run off
can get a cheap TDS meter off Amazon

i hate to tell you this, but that soil needs to get changed.

Plant is doing fine now thought I'd post an update with the solution if it can help others.

So my cousin introduced me to a friend that works at a nursery after I mentioned it. They stopped by on Wednesday morning to hopefully help out. She told me the plant actually looks pretty good except that it needs a feeding. She told me to apply some of my garden lime to correct for the low ph which is most likely caused by the acid used in fish fertilizer production as an anti microbial during production. After she left I top dressed my plant with some fertilizers I use for flower. On her advice I cleaned up the canopy in preperation for flower cycle, removed the dead material. She said just give it a few days to recover and flip as normal and that it should do fine. She stopped by last night after work and brought me some potassium silicate to add to watering through bloom.

Good friend, she is definitely pointing you in the right direction. Often times, less is more. I see a lot of involvement with the plant in initial post.

Let soil dry out, sounds over watered at a minimum. That Fish fertilizer is no good, way to acidic for cannabis. I've done it. Use it for the garden outside.

Listen to your friend and try to "help" the plant less. Just give em what they need and let genetics do the rest.

Also, not sure what temps/rh is, but read about VPD when you have a chance. Best of luck!

I wanted to try starting with spending little money so I have just been using what I have on hand which is mostly fruit/vegetables I grow outside so fish fertilizer and other things I have a lot of is what I have been using. I did just put together a DWC setup and will be going that route from now on. This plant is most likely the last I grow in soil.

You're right, my experience with houseplants and my outside garden has also taught me that less is usually more and that its easy to kill them with to much attention.

My temps have been mostly between 70-76 with RH @30-40. When lights go out the temps can drop to 65 but mostly stay at 70+. I just added a small humidifier and RH has now been between 40-55. Definitely looking into VPD as well as other stuff.

@geemonty you're already on the right track, you'll get there. you already have an advantage over most with outside gardening experience, you'll adjust to the differences and be fine. Good job with RH increase. Keep up the good work! Happy growing

For me, soil has to be ~5.7-6.0 pH for cannabis to grow well
