It would help immensely if you would give more info feeding schedule, nutrient mix, lighting, The more info you give will help immensely to diagnose your ailment:)Unfortunately woke up this morning to this little guy looking very sickly. Haven’t a clue what’s going on. Any ideas? New to the form so apologies in advance. Thanks!
So managed to get a water quality test online though it’s from 2017 I did talk to someone and apparently they are always a year behind due to checking the numbers or whatever but I talked to a guy who does the testing and said nothing serious should changed and it should basically be all the same MAYBE with a slight change of any.
Thanks for the help! What makes you think it’s a phosphorus def? And how would I go about fixing it?
If it started from the new leaves that is a calcium deficiency. If from the bottom up mag. But it has more problems now.
My guess is too much calcium blocked the roots. Calcium is a large ion and difficult to uptake.
150 ppm is ideal for tap water. Yours is likely very alkaline with double that. And mega crop has calcium and silica included. I bet ph is high as well in the res.
Best course of action would be to mix filtered (ro) water to your tap water 50/50.
Or you could use a hard water nute formula like the hard water 3 part gh nutes with your tap water.
Or a nute like jacks where you can lower or eliminate calcium.
Ot botanicare kind trio the base bottle is just calcium nitrate so you can customize like they do with jacks 321.
Hope this helps. Read about calcium.
What does your nuitrient chart say you should be on for the age of your plant? At a 1000ppm you should have enough Calcium, and like MIMG says you have a bad Calcium def. Your water is as hard as it can get with out setting, you will have Cal/Mag problems in DWC, my water is only 260ppm, and I suffer a lot with Cal and Mag defs if I take my eye off the ball.
Assuming everything's in order, if that's the original Mega crop a lot of LED grow have had calcium issues with it. I myself had a calcium problem for the first time ever when I used it as well, that said there's a new megacrop formulation now which supposedly addresses the calcium issue, good luckI've look around and also came to mag def as well. Any thoughts?
