Deficiency, burn, or nothing serious?

It almost looks like a lockout of some sort. Are you using tap water? reverse osmosis?

If your using R/O, make sure to add about 5 ml of Calcium-Magnesium supplement per gallon of water. R/O systems and water softeners remove all of those elements.

If your ph is a little off I would begin to suspect Phosphorus is being locked out or just a lack of it.

Cannabis can thrive under such massive humidity differences that humidity will almost NEVER be a factor for development. Yes, you can stress the hell out of a plant with 90% humidity or 10% humidity but if you can keep that range in between 30% and 80% you will never have a problem involving humidity...period

I use tap water but I let it sit for 48 hours to let any chlorine evaporate. The tank gets filled up with 10 gallons then I add the nutrients. I check the Ph daily and make sure its around 5.5-6.0
No runoff on DWC. Whatever water the plant uses I replenish daily. Yesterday I had to add a gallon and a half to bring the water in the tank back to 10 gallons.

Okay this guy jack larson is a total idiot. Every post of his is negative and uniformative i doubt he knows anything but how to spew out copy paste info.

Now to actually answer your question. I have the medical cannabis growers bible which shows great pictures of all stages of all specific deficiency's, which i looked up for you. It looks like you have a K and magnesium deficiency.
Both cause the spots on your leaves which means you have had a heavy deficiency for a while now, clear that up quick. Your plants are using allot more nutes now that there in flower bulk up on the p and k. I would use canna pk 13/14 if ur in dwc.

Hey thanks a lot for the info HeavilyMedicated. I'm using the GH flora series three part nutes. 50ml Gro, 100ml Micro and 150ml Bloom in 10 gallons of water is my mixture. I was trying to save a little money by letting my plant go for two weeks before a solution chance but I guess this massive of a plant will suck them up and deplete them pretty quick. Should I do my solution change once a week?

When you find out that these issues are do to lock- uot becouse you are not flushing uot the nutrient salts that have buit up in your soil remember who the idiot was!! no run off is like not having toilet!!

Could you please explain to me (and the board) how one achieves "runoff" in a dwc system?
I'll hang up and listen...

Jack needs to read before he posts. So many people in these forums reply without reading properly. It can send a newbie off on the wrong track. Please reply only if you know WTF you are talking about.

It's f***ing frustrating as a newbie getting bullshit answers from people that don't read!


The OP did not mention how he was monitoring his PH. If your showing signs of deficiency, I think it's probably wise to first check double check the PH or recalibrate your pen. Ive heard PH can be pretty volatile in DWC. Could be that he has crap tap water like I do (although I grow in coco which is different to DWC).

Lol hey guys lets not get all excited and lock the thread due to trolling. Larson, I'm not growing in SOIL. I'm growing in a Deep Water Culture hydroponics system. No soil involved... just add water lol.
I don't have the best way to check Ph (I use drops) but I do check it daily and its in the 5.5 to 6.0 range. I'm pretty confident that nute lockout is not my problem. Perhaps the plant just used up all the nutrients over the two week period. I'm leaning more towards deficiency now and I will change out the solution weekly instead of biweekly like I have been doing.

I really need to get me a bigger fan and get some better airflow in my closed. The buds aren't showing any signs of mold but they smell like shit!
