From the start I’ve been watering with ph 6.5. I just discovered my runoff is 7.1 and I have what I believe to be a zinc deficiency. Similar issue on my previous grow. How can I fix my watering routine such that the ph stays more stable?

What to do? Where am I at now actually? I’m lost and slightly discouraged
When should I add happy frog fruit and bloom? This is my 3rd grow and im 0-2! I have a overfeeding problem but I’ve learned to be corrective and precise with ph and ppm and be pest preventative as well (heavy handed waterer as well..im trying). It’s day 5 of flower and I’m lost

Yellow and skinny growth?
Can anyone tell me whats going wrong here? I'm guessing the tips yellowing is nutrient burn from the MG soil. But the allover yellowing between the veins and skinny growth has me stumped. My first grow did something similar going into flower. I appreciate any tips or suggestions.

Interveinal chlorosis on older and new leaves. Magnesium deficiency?
I've been maintaining my nutrient mix pH at 6.2-6.3 as recommended by Biobizz. However Ive been noticing magnesium deficiency like symptoms on the older and newer leaves. Should I increase my pH to 6.5-6.7 or is this something else entirely?
