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?Week 7

What to do? Where am I at now actually? I’m lost and slightly discouragedWhen 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 lostLeaves. Veins - yellow between

Update on previous deficiency questionUpdate on previous deficiency question
The leaves got worse, its still only a few so not too bad. After doing some research i think it could be a Manganese, magnesium and/or Sulphur shortage.
I fed some liquid calmag a day ago. I plan to use epsom salt if there is no change6y ago

Continuing calmag deficiencyWhat I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciatedLeaves. Veins - yellow between

PLEASE HELP!!! CalMag deficency?CalMag deficency? Deficency starts on lowest fan leaves. Starts as a shiny spot in between veins that later turns yellow, eventually spreading to whole leaf causing it to die. Uping CalMag in feed and spraying her with CalMag water mix. She responds well at first then spreads.Week 4
