Johny: that pH is fine if your using a soiless mixture; your pH can range from 5.5 to 6.3.
The best range is 5.5 to 5.8 range; a 6.0 range will not cause the problems you are having, unless the pH you have given is not accurate.
Ya, I noticed that too; but that is not caused by the pH; Ph would affect not the upper part of the plant; it happens around the lower to mid section of the plant; the oldest leaves that have been in the mixture.
This is caused by something else; either keeping a high amount of moisture on the leaves in that area; or the plant does not like the heat it's getting; a warm heat causing not cupping but a droopiness look to it.
If it's got moisture stress; then your not letting the bottom of the pot dry up enough. Overwatering can affect oner part of the plant when they are bigger and it's normally either the whole plant which is more common; but if you are not letting the bottom dry out enough your plants will cup like that looking like moisture stress.
Soil dries out in stages when you have enough perlite in there and that your mixture is not cheap.
Cheap soil holds in more moisture around certain areas and others dry as a bone.
Mixtures that are good and have enough perlite will dry out in 3 stages;
Upper,middle and lower parts; if the top parts of the plant is being affected; the very bottom mid to lower part is being kept a little too moist; that is a possibility.
How often are you watering and how much are you watering?
Because if you do overwater your plants; nitrogen gets absorbed less in the soil and can cause a problem like this; bigger plants can sit in water a bit longer without showing signs of moisture stress like small plants; so nitrogen deficiencies can be masked when the real problem is over watering; but in this situation it looks to me it's more of it needs some more rather than over watering, but the lower part of the soil may be staying a bit moist.
