Are you using nutes/ferts? How much if so? I'd say keep your ph between 5.5-6.5.

It could be a few different reasons. Its some kind of burn. Had the same thing happen when i sprayed too much neem oil. But also had it happen when I over fertilized. I'd recommend you flush a few gallons of nute/fert free fresh water. If that rust look actually comes off of the leave onto your fingers, you have a root disease. Add some B vitamin mix if it is the root problem after about 3 gallons of flushing.

hold on man. before you go trying all these things for deficiencys consider this. A) actual deficiencies are one of the rarest things encountered in gardening and from what you say your using nutrients so i doubt it. B) Soil pH of 7 is fine though ideally you want to be between 6.3-6.8. Its hard to know for sure whats wrong without pics but leaves curl down most often as a result of overwatering(most nute def will cause them to curl up, another sign you dont have one.) If you water often, i would bet this is your problem. This would also cause the yellowing. When you overwater, plants are unable to absorb CO2 and cant uptake nutrients. This results in a plant which looks like its experiencing deficiencies. Another likely cause is actually spider mites. After they begin feasting on your plants spots begin to appear where they have been eating. You will notice tears in leaves and yellowing spots which will look dead. You will also notice that this yellowing spreads quick. Look on the undersides of your leaves. If you see black spots or white spots for that matter youcould be in trouble. The white spots are the mites and the black there devilish eggs. Start a miticide immediately if you suspect this and use it every 5 days for atleast 3 weeks to make sure you get them all. Without pics man its hard to say. But once again actual real deficiencies are some of the rarest plant problems out there. Dont be so quick to assume its this. Throw up so pics though and youll get more help. Be sure the photo the tops of the plants, the underside of leaves, and give us a good picture of the branch growth.
