Hello rui i am on my second grow and on one of my plants (gene unknown) and only this one there are some yellow and brownish spots that started on one leave and has quickly spread to all the older leaves and i believe it to be a calcium magnesium problem but i am not 100 % percent sure and would like some help from someone that has had this and what i can do to treat it before it gets worse

my setup is as follows....

3 gallon fabric pots
happy frog soil
temps are always around 76-80*f and humidty around 40
i currently have them just under cfl lights about 9 of them on a rig i made myself
i water them just straight sparklet distilled water no nutrient yet

Happy frog isn't exactly packed with food...you might be better off using your tap water to keep the micro nutes flowing..

There's no way a plant that small in Happy Frog can have too little nutes. I mean - you could grow it with just garden soil with no nutes added and it will be lush and green at that age. It can only be too much love. Remember - it's called weed for a reason. Because it can survive in almost any condition like a champ.

nutrient lockout in the soil ph of runoff may be off



Solution: If the pH of your root zone is off, then your cannabis cannot properly absorb calcium through its roots so the first step is to ensure that you have the correct pH for your growth medium. Different strains of cannabis tend to have different nutrient problems, but calcium, magnesium, and iron deficiencies often appear together in cannabis. Therefore many growers decide to purchase some sort of Calcium-Magnesium (often called Cal-Mag) supplement for their grow room in case this common deficiency appears. I have listed some available Cal-Mag supplements that I have used along below with some general information about each one. After supplementing with Cal-Mag and correcting the pH, you should expect to see new healthy growth within a week.

What is the temperature/humidity of the cultivation area? I just checked mine and it was well over 90 and 28% humidity, and that was after I removed a 105w 2700k cfl. Air circulation is a must, I had her in this tent with these high temps for almost two weeks now, so that illuminates the cause for the calmg and overall stunted growth. I also did not have a 90w led running for most of the time, just turned it back on two days ago, so her temps might have been lower than 90, but definitely were above 78 I know that for sure. Also too much salt in medium will cause nutrient lockout.
