Before the questions I have a post with my setup information and few ok pics called please help droopy plants...I'll note that I'm kinda retarded sometimes so any specific setup information or question clarification needed before ya can answer just lemme know but I'll just post em to start
1. Do different hydroponic systems run at different ph and ppm levels? Like if you took several clones and put one in aero one in dwc etc etc (I'm assuming this is all things similar besides the actually culture ie CO2, ventilation etc) would they basically run different ph and ppm or pretty much the same respectively in each onet throughout the grow?
2. If they are different does the droplet size affect the ppm? Again clones in different setups one at 20 microns and another at 100 microns
3. I know ppm starts low but how low 0 - 150? I have only a basic understanding of osmosis but it would seem that 0 ppm water would tend to pull out nutrients if a plant root cell has 100ppm water...so would 100-150 be better to start or is just plain RO water the best?
4. PH...Where to start...I'm currently at 5.9 and have kept between 5.8-6.0 so far but Zandor posted in Crash420's hydro help thread that 5.2-5.5 is the range for hydroponics...is that the range to start at and keep through seedling, veg, flower, & flush?(Does that range account for nutrient needs of different stages compared to ph vs nute uptake charts) Like is it just that simple it's 5.2-5.5 period...or should you adjust ph as you progress (ie gradually drop down by like .1 per day till you get to 5.2-5.5 and eventually flush/harvest from there) or is there a basic ph range for each of the 4 stages *seedling, veg, flower, flush*?
Since this is my first water grow I've been just using information I can read online I'm at Day 16 of flower and if 5.2-5.5 is definitively the best way to go in practical application I'll definately trust those with experience rather than random charts haha thanks for any help in advance:thumbsup:
