Hey Its true. No one know what soil you're using as well as what nutes you're using so no one can really give you a straight answer. Here is what I suggest for the future. Get GOOD NUTES! The kind from a hydroponic store. Do not use Miricle grow. It is made for real flowers, the kind your grandma loves with all that time release bullshit with it. If you must, then only use half of recomended dosage. VERY IMPORTANT: Even if you have to just water your plants, Add 10-20% of your usual dosage anyways. the idea here is that if you don't, your plant will get something called "nutrient lock" (This is similar to one of the problems why people can't loose their weight. Cut the fat from your diet, and if you have deregulated your bodys metabolism , ANY fat you introduce later, the body will be in a preservations mode and will store all that new fat away Because it thinks it might fall on hard times in the future and need that fat later). It sounds fucked but thats kinda how your plants work with their food. SO I always add a small amount of nutes even when my plants need to hold off of it. Hey I never had a problem yet. Now. Soil. I never bother with ph this ph that! BS. I learned from some pro growers that they don't give a fuck about PH. It sounds wierd but check this out: They grow in something called Promix BX, or promix HP. What is special about those two brands of soilless soil (and that what it is soilless) is that it will regulate the PH for you! Thats right. Give your girls your standard tap water and not give a fuck about PH, cause promix will regulate it. Remember it has to be the BX or HP. Anyways the watering should basically work like this: WET, DRY, WET DRY. Some plants will take up water differently but you should only water when the pot is lighter as opposed to heavier in weight, you have to determine that yourself, so stick your finger in that soil too. Keep lots of fresh air circulating at all times as this will most importantly encourage strong stems and good vent is allways very much needed for avoiding mould. Hey, I hope you're growing under a real light, that is a 1000 W bulb. See this, if you're you're in your vegetative stage you could probably use flourescent bulbs, whatever. Come time to start blooming and you need real power. All instructions on those real hydroponic nutes assume you're gonna grow your shit with a standard 1000W bulb, the problem here happens when you give your plants the food and there is simply not enough light for the plant to convert all that foor into its usable form, so if you're gonna be using a 400 w bulb for your grow room the cut your nute giving in half. Anyways I hope this helps you a bit, let me know how it turns out when you're trying some of this info.
Growing the best weed is not that difficult!
Happy Growing dude!
