You have a couple of issues now FYI: cal mag should be added. The one plant taco’ing: temps high or over watering.

How about filling this out and be as complete as possible. If soil, WHAT soil etc. Are you measuring PH and if so how?

Welcome to the group. First the type of soil is very important because if it has time released nutrients add like miracle grow and others the ones that say feeds for 3-6 months make it difficult to add nutes because the nutes you add mix with time released nutes and can cause nute burn. The fertilizer you showed is not right for plants in veg it’s to low in nitrogen. Basically the percentages are not right and your plants show signs of a little bit of issues going on I am not as experienced as others here so I don’t want to add my advise so wait for more experienced growers to help

  • Vessels: Pots, Grow beds, Buckets, Troths : in pots of maybe 3 gallons
  • PH of Water, Solution, runoff (if Applicable): ph of my tap water is 6.5 measured with this ph pen
  • PPM/TDS or EC of nutrient solution if applicable: dont have any ppm/tds meter
  • Indoor or Outdoor : outdoor
  • Light system : sunligh
  • Temps; Day, Night : day 25C/ night around 15C but had a hot streak last week around 30C
  • Humidity; Day, Night : around 60-70% maybe more in hot day… variable

I know i got some issues, first time growing and i was not really prepared to be honest. I found those seeds and wanted to try something with them so here i am struggling with the growing of 3 little plants! My goal is to be able to make it to harvest time and learn in the processus to make it better for next year, im already planning to buy fem or auto seeds that will be maybe easier to grow!

Plant 1:

Plant 2:

Plant 3


I change the spot to a more “ventillated” area this morning to see if this gonna help for the heat stress, maybe the deck section was too hot for them! And that’s why i put them in white containers to see if it’s gonna help to keep roots cooler.

Plant 1 is already flowering since 1 or 2 week from now, i experienced some issues with this one when transitioning to flowering, a lot a leaves were dying so i remove them and the side and tips turned brown and crispy, but now its seem to be stable!

Plant 2 just show me her sex 3 days ago and its a female, i think this one is the healtier! Had some issues with it too but not as bad as the others…

Plant 3 suffer from heat stress like you said , and certainly others issues too but always be in the same spot as the others, and giving around the same amount of water for the 3.

I try to water them each 2-3 days, let the soil dry between each watering, i dont think i overwatered them :man_shrugging:t2: The only thing i put over the soil one time was a little bit of tomato fertilizer (6-12-12) and i watered after!
I bought this fertilizer for the flowering stage, some friend recommended it to have bigger buds at the end but i’ve not used it yet !

So If you have any advice to help keep those girls as healty as possible until the harvest ill be greatful :pray:
This is like a “training” for me, i learn from the mistake i made and all i can do is improve my growing experienced for next year! Im in Quebec city, Canada if that can help to figure out my growing environment.

Oh and my name is Nic :raising_hand_man:t2:
Thanks in advance


I think you are off to a good start. The heat stress can be managed: when it’s too hot for you to be in the sun just put em in shade. Under a tree is fantastic. Rule of thumb is if it’s comfortable for people it’s good for cannabis.

I would let my tap water stand for a day to eliminate any chlorine FYI.

It would be nice to have a runoff reading because it’s possible your plants are getting hungry. Hate to introduce nutes if they aren’t. A cheap TDS meter is all you need for that.


For the “run off reading” im not sure what you mean, i don’t have any water coming out of my pot, there is a scoup attach at the bottom of the pot with a drain hole but nothing as ever spiting out that hole… should i water enough to see water coming out the bottom ?!
And i put the plant with heat stress under the gazebo between 11am and 2-3pm and but it back under the sun and the end of the afternoon, going to do that for next couple days and hope the leaves stop taco’ing
