Are feeding them excessive amounts of fertilizer? Give us more details as to everything that's going on, your set up, temps, nutes, etc
i have 4 plants i have them going 24hr light schedule with 2 100 watt daylight bulb 5000K cfls for each plant. I mixed the soil some shake n feed and perlite into the pot. i give them about half of the recommended amount of liquid feed and i water them almost twice a day depending on the weather. I live in southern cali weather about 90 degrees for high and around 75 for lows. I usually take them outside so they can get real sunlight for about 6 hours them put them inside a box i setup and it gets 90 degrees max inside the box. I have a swap cooler above the box to cool it down, the box also has good airflow.
watering twice a day huh? Well stop doing that for starters Sent from my HUAWEI-M835 using Grasscity Forum mobile app
Id bump up to 6500k bulbs, and definetly dont water them twice a day, thats the number 1 mistake new growers get A comment on the soil...how can it protect against both under, and over watered? Also it might be beneficial to either commit to outdoor or indoor growing, switching inbetween is asking for an infestation
Also, that soil looks to have nutrients in it already, so you probably dont need to use the ones u got for awhile. so maybe its a lockout due to having too much of something.
To use miracle grow effectively for cannabis, try using only 1/4 strength. It is not meant for cannabis. The ratios for the soil are actually okay for vegging your plants, but I have a feeling you have over done it by adding more already. I suggest you give it a rest with the fertilizer and feed the only water for the next 3 weeks or so.
