What should I be adjusting my PH to?

[pinchegordo]

Hey so I have just got back into growing and have just started using a soilless potting mix,I am using Botanicare ReadyMix now I have been adjusting my Ph to 6.3-6.5 but I am now thinkin maybe I should have been adjusting it to around 5.8 like hydro... Anyone know? My plants are about 6 weeks into flower and are really yellowed up like I'm locked up due to ph issue

soiless mixes you adjust as if they were soil. so the 6.3-6.5 is perfect. i use sunshine #4 which is soiless and my pH is always in that range. coco is 6.0 and hydro 5.8

the yellowing could be from a deficiency or over fertilization. what are nutes and ppm levels?

good luck

I aim for 5.8 to 6.3, but I honestly doubt you'll notice the difference from where your at. At weeks six seeing some of the older leaves turn completely yellow and die off is normal. Even if your tips are a tiny bit burnt I wouldn't worry. Pay attention to the flowers. How do they look?
