Grow Mediums smerkeys 2300 wat vipar led dwc thinkdifferent grow

I get what your saying mate the girl in the corner is drinking more than the other two and the ph has been dropping to 5.5 on that one but it's the healthiest looking and the biggest and when I uped the ppm it was the one wich I got bang on 550. I'm going to keep a close eye on the ph over the next few days and hopefully it will stabilise what you think mate

Nice looking roots you got there, the color of the LED is kind of washing it out a bit. What is your RH during lights on and lights off? I have found that RH directly affects PPM's which in turn can effect PH. My RH was out of control at one point which caused my plants to drive more water then nutes, making my ppm's skyrocket and bottoming out my PH. Once i corrected my RH everything else stablized.

Are you running a beneficial tea?
 
Im guessing he means relative humidity mate
 
I've heard so many good things about beneficial teas and I'd love to try it but I don't know how to make it or use it as I've always used canna nutes. I'm still trying to work out what rh means. My rez temps stay at 19 20 my room temp when light s are on is 23 max lights off 18.
 
Rh, relative humidity - moisture in the air
 
Whats the best rh. I think mine is in the middle 40s. I'll put exactly what it is when the lights come bk on
 
I've found out why my Ph kept drooping. My Ph pen wasn't calabrated right it was out by .3 so when it was reading 5.8 it was realy 5.0 so I changed all the rezez as it was rez change day anyway ppm 600 Ph 5.8 and that was yesterday and today the Ph rise to 5.9 6.0. They all look healthy. It's there second week on veg nutes. And they have showed there sex. It's the last week of veg nutes depending on the ppm rising or falling. Is that right Cocha mate I carnt remember is it if it falls there ready for flores nutes
 
Here's how they look week 4

niiiice ! :Sharing One: I would keep them on veg 1 more week then swap to frores bro .You swap earlier if your after a quick grow or a bit longer for more stretch ( theoretically ) .

A drop in PH can be a sign the plant wants bloom feed ,but if thats already falling a week or two after sex is roughly when most people swap :Cool bud:
