Don't flush unless you have to. It's kinda a like heart surgery. Definitely don't want to do it if it's not necessary. Just start off slow and slowly increase the strength.

I was always told if switching nutrients, always flush out the old... that way you know what the new is doing to your plant😀
Happy Growing!

Math check.Making my own bloom booster, aiming for a 0-10-10 ratio. I use powders and know that 1 tsp = 5ml. If make up a 1 litre solution, to achieve 0-10-10 would that mean 980ml of water 2 tsp of mono-ammonium phosphate 2 tsp of potassium sulphate?Week 5

Terpinator (During Flush or Not)For those of you who use Terpinator, do you prefer using it up until harvest or do you prefer still cutting out everything during your flush? I know its' advertised as being able to use during flush so I'm not worried it's unsafe. Just figured I'd see what my fellow growers like!Week 10

Hydroponic PPM and feeding. How do I match magnesium sulphate to potassium for flowering??Do I got this right? Hydroponic Flowering cannabis eats at a rate of 1-1-2 and for maximum useage, feeding 1-1-2 makes sense. Extra nutes outside the ratio is wasted and extra. You want highest PPM possible before burning. Will extra Cal-Mag burn roots/leaves?Feeding. Other

Nutrient burn?I believe I overfertilized this week. I am using a four bucket DWS system with Reservoir bucket. This is the last week of my veg and I might’ve been heavy handed with the fertilizer. At one point my solution was 1844 ppm. I usually run itbetween 8 to 1200 ppm. I delutedd the solution in half. I didn’t have time to change it all because the lights are going out. Do you think this is nutrient burn? ThanksLeaves. Edges burnt

Coco grow: the EC of my runoff is consistently 0.2 mS/cm lower as what goes in (1.1 in at this time, runoff is at 0.9). Also, PH of runoff is at 5.8, while 6,5 goes in. Is this a problem? What causes this? Its been 8 days since germination and they look healthy.Feeding. Chemical composition
