What's up with my marijuana plants!?


#1

A question from a fellow grower:

i was wondering if you could help me decied whats up with my plants, the first pic shows my most affected plant. is affecting most plants, except my biggest one, to some degree.
i also wanted to show you this cool leaf in the second pic, and also my seedlings are being affected as you can see in the third pic. it could be to much nutes, as i give recommende dose of multi trace, easy grow, cal/nitro and epsom salts, two waterings out of three the third of wich is pure water. my ph metre is on the way, i have flushed with pure water amd given gypsum for calcium and epsom salts for magnesium. what do you think it could be, i am also wondering if hps lights always make lines of darkness and light when looked at through a digital camera, as you can see in the fourth pic. my biggest plant is still on a veg cycle, probably not for long.
Sorry if reading this was at all boring, just thought you might have some good advice.
and finally a pic of my biggest in fifth pic. and leaf deterioration begins in sixth pics

Yes the HPS can cause lines in some cameras. It’s a frequency/Hertz thing.

It looks like it could be a pH thing and/or a too much nutrients thing. Are you checking the EC/TDS/PPM of the soil’s run off? Or checking the soil fertility/nutrient concentration with a soil probe? When you get the pH pen you can test the runoff for an idea of what the pH is at the roots, which is where it counts. pH soil probes can also work for helping determine the pH at the roots zone.

Super skunk outside fem. .


How do you bring down the pH level it is at 6.5-7.5

It’s hard to tell, but yes those tops don’t look as full and healthy as they could be. We could use more info.

Let’s get you started with a ILGM support ticket that Latewood had first developed. It’s is a great checklist of things in your plant’s environment that might help give us an idea of what could be going wrong.

Answer all the relevant questions the best you can, if you do not know, or do not use something, just say so or put ‘NA’.

ILGM Support Ticket:

What is the strain and type(strain name, unknown bag seed, regular seeds, feminized seeds, auto-flower, etc)?

Indoor or Outdoor? If outdoor, planted in ground or in a container?

Size of space (max height and area, length/width)?

Soil or Hydro? Type of Medium used? System type?

pH? Of the soil or medium (root zone/reservoir/runoff) and of the water and/or nutrient mix that is fed to the plant?

Type and strength of nutrients used? NPK? EC/TDS/PPM levels?

Temperature? Day vs. night temp or highest and lowest temps? Root zone temps?

Humidity %?

Light system/watts/lumens/FLUX/PAR?

Ventilation system? Size? CFM? CO2? AC, Humidifier, De-humidifier?

Number “weeks/days” from into Season, Vegetative Growth or Bloom/flowering?

Add anything else you feel would help us give you a most informed answer. Feel free to elaborate, but try to be brief and to the point. Short and to the point questions and facts will help us help you :slight_smile:
