Rapid yellowing of lower leaves. Any ideas?

Hi riu,
I have been battling pm and used a systemic fungicide about two weeks ago which seems to have fixed the problem. I lost a lot of lower leaves during this time which I attribute to the fungus that was running through my plants. Is the yellowing I am seeing now due to the plants being infected or is it a feeding issue? I mainly just feed them water as I am waiting for payday to get some more nutes as I am on a very tight budget. Any experts out there want to chime in and tell me whats going on? I'm a few weeks into flower and am worried I may lose the whole crop. Any ideas?

Is it in a pot? Looks like it needs a good flushing, then some bloom nutes.

Also, consider removing some fan leaves. The plant would do a lot better with a minor prunning. It would open her up and help against pests and fungus. It will definitely help against powder mildew.

Farmers hat you shouldn't have said taking a few leafs lmao you will know why soon.

Looks like cal mag to me,

outdoors no need for defoliation in my opinion.

Try invest in some cal meg aswel as bloom nutes buddy...

Defoliating a recovering plant is gonna ruin stuff more and really slow growth even more

, I defoliate but do it from vegg and little in flower indoor. (don't do it tho please )

I am a noob lol, I'd wait for Ze experts
Hope it helps

I have grown this crop from seed for less than a hundred bucks so far. Most of that was spent on the plastic pots. I will be happy to harvest anything at all to be honest. In saying that I can in no way afford to fork out for expensive flowering nutes. I am just going to buy some basic $14 tomato food and go with that. It says it has calcium and magnesium in it as well as other trace elements. Two of the plants are only a week or two away from harvest and if I chopped them down today I would have more than what I spent on this grow. Its been mostly a learning experience using bagseed on the cheap to get an idea for next year and what not to do. I know I overwatered them for a while in veg and I think this may have caused root problems. I will be curious to see the root ball when they finish. Getting on the home stretch now and am looking forward to cutting these bitches down. I am not a fan of pulling leaves off unless they are damaged or sick. Leaves provide energy for bud formation. less leaves = less bud. Don't have to have a degree in botany to know that's a silly idea.

All my vegg and bloom nutes + addetives together cost 35 pounds and I'm growing for my self too....
Soil is 7 quid every two harvests aswel

Just go to the hydro shop you can buy small bottles very cheap and it should do better.

Good luck mate and hope it works out

I currently have three in vegg from some nice budd that had seeds lol, some of them are killers buddy In the past.

These are unknown budd so I called em anonymous.
