riddle,
had to go back and reread page 36 (and another 5-6 pages besides) to remember which post you meant. I'm still in the learning to read my plants stage, because things keep being contradictory (like the soil being dry but the plants showing no sign they are thirsty). I'm also trying to learn when they want nutes since they hadn't been given any until a four days ago. I know my lack of experience is probably making me worry more then i should, but i don't want to kill any of them by not being worried enough either. Try to bear with me- i do learn quickly, but the information from you and ub is scattered over so many pages that i can't always find what it when i want to.
my logic on the nutes went sort of like this. Nine days ago i gave the girls a shower, and they reponded about the way you said to expect and put on a big growth spurt. But, they are still relatively small to wick it up fast and the soil 2+ inches down still felt a bit moist 4 days later (though the top 2 inches were bone dry). I waited an extra day (4 days ago) and gave them a decent drink with 1/2 strength nutes at that time. Now, since the half strength nutes didn't burn them and it looks like the plants are developing a deficiency it seemed logical to me that the my girls needed more then 1/2 strength, which is why i was talking about full strength last night.
Frankly, i'm still not sure i understand exactly how you're timing your feedings and rain showers. It seems like you are making it rain, letting things dry out a bit, then feeding, waiting for it to dry out a bit, making it rain, etc, and you're doing a step every couple of days. I understand your plant is bigger then mine and drinks more/wicks faster, but how can you be sure you don't have more moisture down deep then you think you do? So far the only time my plants have started to show any signs of being thirsty was when i let them go 5 days without a drink (that was the day i made it rain), so i still haven't gotten an exact feel for how long their cycle will be. I was thinking about making it rain today, but with them showing nute problems i figured it was better to give them a few cups of water with nutes before i made it rain again. Btw, my girls are still vegging (day 19 since they were transplanted). I know you said doing this to plants that were vegging would create trees, but since thats my goal anyway it made sense to go ahead and get started.
