Hi there mate it seems that this particular soil mix tends to be a bit low on the ph scale and a small side dressing of Dolomite lime is usually beneficial. Maybe it tends to be more of an issue during flower because your plants are eating up certain nutrients within the soil thus raising or lowering the ph. I also found a link to others having your problem check it out https://forum.grasscity.com/threads/roots-organic-soil-problems.785317/ Hope I have helped mate

Dolomitic lime is calcium magnesium carbonate. It has something like 20% calcium and 10% magnesium. Pre-mix dolomite lime in your soil next time around. At this point and time what you could do is PH your next feed at 6.8 to balance your soil and finish at 6.5. It takes some time for the dolomite lime to dissolve and neutralize your soil PH level therefore if you are considering adding it now you'll need to buy the powder.
