As long as the tank is completely devoid of salt then no worries. I would venture to guess at one point in the grow it had salt in it. I have seen many a plant look just like yours because of water softeners and sodium build up in the medium.
I am going to do that as soon as I get my mini fridge converted into a veg unit. Is it necessary to use any rooting gels?
.
Yes. Its normal but there doesn't seem to be any cal in it either. Also the FF hydro nutes don't have much cal or mag either. According to roseman, if the leaf tips are curling upward then it can be a indication of a mag deficiency/heat stress. Since that is happening and the veins are dark green in comparison to the other it makes sense. So how should I go about correcting the issues? I know I messed up and nute burned them already. Now what if I do the 8-step remedy and a res change with epsom salt, 2 tsp of tiger bloom, and 1 tbsp Big bloom?
Thank you.
"I have seen many a plant look just like yours because of water softeners and sodium build up in the medium." I don't have a softening system but you mention sodium build up within the medium. I am using rockwool and hydroton in the netpots. I have not been pouring water over them because the roots are in the water and the pump has been removed. If their is a buildup of salts in the medium do I just pour ph-water through them a few times?
not necessary but they do help.
the rising PPM is a indication of temprature rising....when the water gets warmer the ions move faster thus giving you a higher PPM reading.
i really dont think this is your issue. like i said before try crushing up some tums and dissolving them in water for Ca, if you dont want to do that monday is not too far away. Ca is Ca though the Ca you need is the same Ca that comes in milk and tums.
Has zero to do with hard water in this case. Its all about the sodium content of water that has been processed by a water softener(if he has one, he did ask)........
No softener then gotta say is a mag issue. Sodium build up be it from water from a softened system or improper/abuse use of pH ups can cause this very issue. And as Matt mentioned. Find out what the 140 ppm in your water consists of. If its mainly calcium then that could also be inhibiting the magnesium uptake. 3:1 ratio cal to mag is the baseline most shoot for.....c
Dr. Lynette Morgan knows her shit when it comes to hydro. You probably wont see her name pop up in cannabis mags. But elsewhere her words are listened too for sure. She knows plants and hydro.......
Yeah it is difficult to manage in dwc. Especially the big bloom- since its so brown/sandy it settles at the bottom. You gotta have something circulating the solution. I try to stir it by hand every time I check the ph. It doesn't color the roots to much but there is a slight tint.
I already posted what the water contained. There seems to be a high about of sodium but this is based of a 2011 study. Nevertheless the ph has been 7 as they report. Here it is again:
I will look into that for my next grow. Have you guys ever tried Stealth Hydroponic nutrients? Roseman and other's have used them in their dwc grows with good results. I used it my last grow it was a lot easier to maintain then FF (my experience I am sure other FF nute growers are much better at it and it is easy for them).
doubt it. Hermies are cause more by enviormental stressors than physical stressors
