Cannabis Plant and Pest Problem Solver: Pictorial

[Tsilo]

It can easily take a month, or more, just for the clone to transition from flower into veg. It might be time for flowering on your clock, but that plant's clock is saying, "too soon!"

What light schedule are you using?

18/6 but I'll proceed with flowering let's see what comes out of this stressed out clone I have another clone and goint to take clones from other one hope something will work out of this experiment first time growing from clones

You can give it a shot but I'd be willing to be she hermies on you if you try to flower her now. My recommendation, if you want to get some good, non-seeded meds, is to get her under 24/0 until you see five-fingered leaves. If she's been vegging a month under 18/6, you should be pretty close to seeing the transition. It would suck to start finding nanners in three weeks and have to start from scratch then with a fresh clone or seed.

NO-PEST STRIPS work magic if used properly. I quarantine anything and everything in a NO-PEST STRIP room before anything enters garden. Have used them to get rid of problem spider mites for 20 years with very positive results.

This morning in the tent I notice the two Original Skunk #1 plants leaves are turning upwards. It is not showing on any of the other strains.
Here are the two plants, they are the shorter of the other two strains, 6 plants.

No tip burn and the buds look good overall.
Here are all the plants in the 4x4

Any thoughts?

Great info, very comprehensive. I’ve bookmarked to reference as needed during my first grow now. Already helpful, appears I have a low nitrogen issue to resolve.

 

[Trynasmokemesum]

My first indoor grow dont know what is going on run off after watering 5.3 with water that was 6.5 what is going on cal mag needed? Not sure they are young i adjustes the lights to 28in above plants both swi

 

[Trynasmokemesum]

Lights now 32 inches and both switches flipped seeing good growth but some yellowiing

Here is a ready reckoner for Cannabis plant and pest problems. It has been put together by a master grower. I have edited for content and added to as needed. I hope you learn from this treatise.

Great article, I have added to my sig, thanks @420

That's a Magnesium deficiency. Try adding some Cal-Mag or Epsom Salt

Thank you should I use a larger than usually amount or just what suggested by manufacturer?

 

[Mr. Krip]

Recommended dosage (usually 1 tsp per gallon for Cal-Mag) should be fine.

FYI, when you see the yellowing between the leaf veins (interveinal chlorosis), starting at the outer edges, on the lower growth, it indicates Magnesium deficiency.

So I just found that my plants are starting to yellow and turn brown along the leaf margin. I had fed them a tea steeped from bat guano, liquid kelp and worm castings a few days before this happened. By looking at the photo's in the article at the beginning of this thread, it appears to me to be nutrient lock-out. Would you agree? All feed-back is welcome.

Excellent post.....I have a question re soilless mediums. Is Canna Terra Professional considered a soilless medium? Or is that in between soilless and soil?

TIA Vadim

No, it is a decent minerally enriched soil that uses bark instead of perlite for aeration. Canna Coco is their soilless product.

looks like a phosphorus deficiency... maybe a lockout... impossible to guess what is causing it without knowing more about your grow. How about starting a thread based on your question so more people will find you?

 

[gallito]

thanks, i'll try that

 

[gallito]

guess i should have posted a new thread re: this subject, but being relatively new to this database, I incorporated it in my grow journal for this year
