Wow, reading all the issues of folks growing. Step back folks and look at what problems you have.
1. TOO MUCH FERTILIZER.
2. TOO MUCH WATER.
3. NOT GOOD LIGHTING.
4. Not letting nature take it's course.
The first three are abundant in all the threads related to grow issues. This is getting made way too complicated and expensive.
REMEMBER before the 60's it was only a WEED Weeds grow naturally without much water, much tending, no fertilizer unless the crop they infest gets some.....
I will be offing an E-book in the future on this topic, but for now, folks, just let your plant grow and leave it alone.
My basics are:
1. Good soil such as Fox Farm products....not miracle grow or some other super grow crap from HD...the fertilizers are not consistently mixed and burn the plants.
2. Moist soil, not wet. FEEL how heavy the pot is and LEARN what a dry pot feels like. Tend the top soil to also monitor the moisture, bottom can be soaked and the top dry.
3. Minimums of 400w MH and 600 HPS (1000 better).
4. Keep air flowing through the rooms if the lights are on.
I only give a little lawn fertilizer when they go to the flower room. I am told I grow the best stuff my friends have ever enjoyed. I can't tell I use so much butter, I forgot what it is like to get the buzz.
What I am trying to say is, and I know how hard it is for a first timer, but let the plants grow. They only need light and water and a comfortable temperature.
