Help a guy who is a noob to plant problems

Hi guys. I got a issue with a few leafs. The pic tells all.

My setup is the following

-600w hps
-coco hempy
-7g maxi bloom per gallon of water
-temp is below 80 at all times
-humidity is low, but I use winter air to cool my grow not sure if it's a issue or not
-I grow vertically bare bulb
-I keep ph as close to 5.8 as possible.


If you need anything else let me know. I think I covered everything. It isn't a bunch of leafs maybe 10 leafs total and they are in the lower portion of the plant. I was told its from not using cal/mag but I was told I didn't need cal/mag cause maxi bloom has enough already in it, and plus I use well water from the north east us.


edit- I originally thought I was splashing nute water on the leafs but I took the lower 3 inches or so off the plant for easier watering and I just looked last night and I seen them again. No I didn't tear the leafs off but these are progression leafs. For the people who might get confused on what I'm saying there has been more then last time it's progressing

do you filter the well water, or have you tested it to see how many ppm it is? well water can have alot of CA. and salt in it so you may have a CA. build up and it caused lock out. you may have to do a flush

no I don't filter the well water. I don't got a ppm meter to test ppm but a ppm meter is next on my lost. When I water, I make sure I got a lot of run off honestly I hate to do a flush cause they are tied to a vertical scrog

Any others?

Give them a dose of epsom salts. 1 tea per gallon of water.

I got a bit of cal mag from my soil grows. It's botanicare should I give them some of that? I got Epsom salts too but is 1tsp 7 grams just like maxi?

Anyone else? I would like to get this sorted since I just flipped lights a few days ago. I want to maximize yield, I'm not sure if this will even effect it.. Doesn't seem to be much of a issue but I'm not a expert lol.

Well I guess I'll try Epsom salts then and see if that fixes it.

I'll check back either later or tomorrow to see if any other replies.

IMO doesn't look like a Mg problem. Dose look like a Cal problem tho. It would help greatly if we could see a pic of the whole plant. I use coco and maxi as well. I have to sup cal/mg + 1g/gal epson my tap water is 220, and I still have to add cal and Mg

I took pics of them yesterday but it's with my hps on. My journal has the whole grow. If you need additional pics, I can try to get.

The browning in the leaf on the sides looks very much like ph issues I had when mine were a bit out of whack but not sure that lines up with the spottage on the leaf

My ph has never been above 6.2. I try to keep it lower them that but it takes hours to do a 20 gallon res lol. Would take even longer to do per gallon.

Still need to get this issue fixed. I would like more opinions...

Still no replies

Would like more opinions. Lights are off for another 7 hours so I can't take more pics. I'm doing a res change today or tomorrow so I would like to add whatever I need with the fresh res

Still need answer.....

Wow this is the longest time without opinions..maybe 4 opinions? Might have to post in newbie central

If you domt post a picture of the whole plant its hard to diagnose. One leaf doesnt really tell much of a story. At the end of flower some plants dont have a green leaf left on em. I find as soon as flower starts i start loseing leaves bit when the leaves get trimmed off theres nothing but green bud underneath.
