SOIL Dry leaves on 1 SIDE of plant

[lmyers]

Can anyone help? I have about 18 plants, some are indoors and several are outside. This is the only one that seems to be drying up. It occurred almost overnight. On ONE SIDE only, leaves are forming large dry spots. If the problem was rising up the plant I would assume it is a nitrogen deficiency. Could it be ph problems caused by rainfall?
I would appreciate any thoughts or suggestions.
Thanks in advance.

If that happened overnight I have to say someone sprayed (accidentally or intentionally) something on those leaves.
You said outside ? Could engine exhaust have blown on it that evening or night?

Without more info thats all I've got. Good luck. They were getting good size to em too.

Speaking of which...that is kinda big for that pot. Not saying you can't finish it out there, just keep a close eye for stress.

Thanks, I am using a 5 gal. cloth pot-- thought it would be plenty big. Now I am a little fearful of replanting. Do you think it's too late to top?

One foot per gallon is best . If your plants are over 5 feet it is best to go with a bigger pot . The bigger the pot the bigger the plant can grow

Are you using quality neuts? If it were mine I'd give a good flush with ph'd water and finish flush with light neuts and cal-mag. When I have a plant growing to tall I use a tomato cage and supercrop the tallest over the top of the cage and gently tie down. Five gal. ought to big enough to get the job done.
