Hello boys and girls ✌️
Could someone help me on this green decoloration. I raised to 300ppm and the conditions stay the same as above. I just sprayed them with tap water (6.7pH) for like 3 days to raise some humidity. Could it be related? Could it be a lack of nutes?
Hey Growmie,
You're having a magnesium deficiency, you can tell from the light green or yellow coloring that's to show on the veins and edges of the lower & older leaves – this is one of the classic signs of a magnesium deficiency. You may also see red stems. Often with this deficiency, the magnesium is present, but the roots cannot absorb the magnesium properly due to an improper pH. Therefore it is very important to maintain the correct pH (and make sure the pH does not get too low/acidic) in order to avoid a magnesium deficiency. Hopefully, I answered your question and remember Happy Growing and Free your mind one puff at a time.
Thank you for the replies. I flushed the medium and raised the solution to 300ppm at 5.8 pH. I aimed for nutrient lockout, if the problem persists I will raise the solution to 400ppm. If there is someone who could help me on this, I would appreciate. Keep good boys and girls ✌️
Because of my attention and growmies help, I fixed the lack of magnesium. This lack was caused by a nutrient lockout on my medium due to a low pH. I identify the problem, it was residing on a malfunctioning in the cheap pen I bought. Yeah, you need to spend good money on the measuring instruments, it’s very important to every medium, even more on hydroponics. I had this bottles of pH perfect and I started using them, since I can’t get a pH pen for now. I think the science beyond that is quite simple and I trust the solution. Keep it low, so far so good, But I’m open to any problems that may come up. Thank you 🙏
Hulkberry still have not started the flowering process. I’ve corrected this magnesium deficiency today with 1,5ml/L of GHE Cal-Mag. Let’s see next week 🙏
