Chernobyl is fucking serious shit!! I want to get some of those seeds fer sure. It had one of the most distinct smells and tastes i had ever experienced up until that breed. I was also going to add in about the different plant species but some1 mentioned that the blueberry was indica dom. From this you can decipher a great from plant to plant, different traits and things to look for.
My strain whatever it may be is definitely a indica, by the leaves and the height of the plant, just the basic structure of the plant. I also wanted to mention i use earth juice nute. they are organic very forgiving and no build up of salts locking out nutes. Sometimes when you grow a certain strain of group of plants long enough, you will be able to just tell right away what they need and what their schedule is. Many growers are able to tell when their plants are done by learning what to look for. its never just one sign. This is true the whole way through.
Over-nuteing can happen before you see the first signs of it by that time you might nute again, so its always wise to just use clean water nearly every other watering, depending on how comfortable you feel what your plants need or can handle.
Remember its good you know under-watering is always better than over-watering, its only too late when the plants wilt. and always water at the start of lights on if you can help it, plants only use the water when its lights on and its important they have good air circulation. Its ok to let the heat build as high as 85 degrees during lights on and flowering plants dont like very high humidity. At night you wont want to go much below 65 degrees 70 D. is fine, until maybe week 10 or 1 1/2 weeks before harvest, then dropping the temp to like 60 at night can help bring out MANY many colors in your plants. Well for me im under a 400w hps ATM
But definitely have a couple/few oscillating fans in the room, blowing fans right on the plants sucks moisture out of them and might not give the full benefit of strengthening the branches. Moving and turning your plants around under the light week to week can be beneficial too.
