What are the beige/brown spots a sign of? Why are ...

Hello my friend😉 For me it's watering! I allow myself to give you the simplest technique to water your little ladies ... Cannabis is a plant with great water needs, but it also tolerates very little excess watering, so it is easy to make mistakes.👍 By following these simple tips you will get an optimal result throughout your culture: Cannabis is a plant that does not like to receive a light watering continuously. It is imperative to water in large quantities, then wait until the soil is dry before watering again! To calculate how much water each plant needs, follow this rule: The volume of water to be given during each watering must represent at least about a quarter of the volume of the pot !!👍 Examples: for a pot of 1L, give 0.25L of water at each watering for a pot of 4L, give 1L of water to each watering for a pot of 12L, give 3L of water with each watering for a pot of 30L, give 7.5L of water with each watering! etc ...🤐 To give such a volume of water, it is often necessary to water in two (see three) times, slowly and uniformly over the entire surface. Have good cups under the pots, they will fill with water that will rise into the pot by capillarity in less than a day. It is also very important to use a good potting soil, with a good water retention capacity but which also ensures good drainage (it must contain perlite, and / or coconut, etc.) Once this watering done, you can see that your pots are very heavy, and are difficult to move. You must now wait a few days by regularly underweighting the jars with your arms. When they are very light again, you can water again !!👍 Hoping to have given the most complete answer possible 😉 May the strength be with you 💪

@DeeCee My guess is a root issue if you have ruled out overwatering and the light isnt too close then one would next investigate whats happening below the surface. A mycorrhizal innoculant may be of benefit as well as raising your ph to 6 or thereabouts

Plant have different needs, and maybe its an underwatering=? well we have been talking alot , and iam sure we can find out whats happening here. Just start with the worst looking plant .
