Hey hey -- I'm looking for some expert advice on my soil. - Growing under 400w MH/HPS. Currently running 18/6 - Plants are in week 4 of veg. Planning on switching to 12/12 this weekend. - Temps between 23C and 28C depending on what I change in the tent (constantly experimenting and improving the grow) - Watering with tap water, Ph of runoff is low for all 3 plants but increasing slowly after each water. Watering is done every few days, depending on the plant/soil. - No nutes yet, holding off till Ph is balanced First real grow, currently using Promix Potting Soil as it seemed to meet the requirements based on my limited understanding of Cannabis nutes. Also using it cause I bought a big bag that would be a shame to waste. The ingredients: NPK breakdown: The ladies: Can someone elaborate on "slow release fertilizer"? Is any one able to make sense of what this fertilizer is? I would love suggestions on organic compounds I could add to balance Ph and increase available nutrient load before I switch to flower... Thanks in advance for the knowledge.
plants look a little over watered, avoid slow release fertilizers. they're great for some plants but the nutritional needs of cannabis change over it's life cycle so you don't want the same nutes the whole time.
Interesting. How do the needs change over the veg cycle? I understand during flower more P and K is good. For watering, I wait until the pots are really light and then I use a moisture meter to double check. Sometimes I'll poke a finger in the dirt to be even more sure. Does it really look like over watering?
