Fan leaves turning light green with spots

Hello, I was wondering what it meant when the fan leaves start turning light green with almost green looking spots. It started with a middle fan leaf then moved down and back up. It eventually turns into a yellow leaf with brownish spots on them.

Anything anyone could contribute will help. I will work on pics for you to help diagnose. Thanks for any help in advance.

Bump for justice with pics.









First 2 pics are leaves that are pretty much fully covered. The third pic is one that is getting close to being light green and mad spotted. The fourth pic is just eye candy.

Sorry for the pics with the light on.

PH tested out to be 6.5
I have realized that the neptunes organic fish fert and seaweed fert state to use a tablespoon each per gallon of water. I have been using a teaspoon. Is it possible that the problem is as simple as not having been giving it enough food? I have maybe fed it 3 times with a hair under a tsp per gallon. Next feed should I use a full tablespoon?

Any help is appreciated.

stop using the fish shit. some plants don't like it at all, and that's generally the result, shown in your pix.

go with a good 3 part formula made for medical cannabis (ie gen.hydroponics or ad. nutes)

Alright, I will check into it. The npk of the fish stuff is only.....2-4-1? Is there anything else that the problem could be?

2-4-1 is high for p, low for k. you could be looking at phos toxicity (which is what it looks like).

i burned the hell out of some pickier strains with fish poo, so i nixed the use of it. i'll use mg in veg, but you can't beat a nute program designed for and tested exclusively on mmj.

I also have some schultz big bloom or w/e which is 10-54-10 (seems intense though, yet to use it) and i have some bat guano that was....1% 10% .02% I believe?

Im a noob and this is my first. Just trying to figure it all out.

So this is potentially a nute burn? Should I go ahead and flush it so i dont further damage the plant? Or just carry on and only feed it water for a while?

throw the shultz away. pot does not like super phosphates.

don't flush, just water and superthrive.

if you can't get to a hydro store, get miracle gro all purpose 24-8-16, and give them a dose of that (level scoop from the small side of the spoon for one gallon). this'll help get them back up and green again. don't feed mg until at least one watering, and try not to super soak them. if your soil feels heavily saturated 24 hours after watering, you're over watering.

Alright, this problem is continuing to own my plant. I noticed that underneath the yellow leaves with the brown necrotic spots on it that the veins are all white. My water leaves look healthy in color but the edges are curling down in.

I gave it some water and a drop of superthrive not so sure how its responding to it. I was thinking perhaps next watering use the neptunes seaweed fert (0-0-1) with another drop of superthrive and possibly a small amount of epsom salts.

Any more help would be appreciated.

same things happenin to me also.

mine looked somewhat like that --i went and bought epson salt and mixed 1 teaspoon per gallon of water and gave her a dose---only been a few days but she looks better
