My marijuana plants have skinny weak stem, fall over

Its the start of sulfur deficiency

What is the best way to add sulphur?

Most flower foods should have it fox farms nutrients have it to be specific the cha ching, open sesame, and beastie bloomz.

Lots of others have it as well, when you add it add very light amount, about a 1/4 tsp per gallon and that should help out

Ok. Thank you!

Yup not a problem

One of my seedlings literally fell over after transplanting from rockwool to soil, choclate haze, i stood it up for a few days and now shes happy as larry, genuinely was like the stem had been cut in half with a knife… stupidly floppy, maybe use some rooting agent or try a different brand/use more of it?

The stalks can be fragile the first two weeks, I personally use bendable straws and position them so the plant leans on them. It is a very common occurrence but will fix itself when plants become more mature. Good luck with your grow!


1st time grower. I’m having the same issue with my girls. Please see pic. This is normal?

Welcome to the forum.

The stretching is caused by inadequate lighting. What are you using for lighting?

It’s just a 60w led bulb. Being this is my 1st grow I didn’t want to start out with a large investment.

Welcome @Cog. @MidwestGuy will not steer you wrong. More light! A lot more!

The only plants that need as much light as cannabis are palm trees, olive trees, and cacti. It will unfortunately require an investment, as you can’t really get a harvest using ordinary LED bulbs.

If budget is a concern then go with 1 plant. A single plant will require a minimum of 200 watts of quality lighting to flower it effectively. Good lighting is going to cost a little over $1 per watt. HLG, AC Infinity, and Spider Farmer all have good lights. HLG offers exceptional quality and they sell refurbished lights on their website that you might be able to get for a good price.

Going outdoors when the weather permits will be another option. The sun is there for us for free.

We can help give guidance on quality if you post those lights that you are interested in before buying.
