I think 5,5-6,5 is ideal for coco, for soil it should be 6,0-7,0. When you drop to 5,5 you are asking for troubles, but its still not so bad. when you drop to 5,0 you will see the troubles soon. Your actual soil pH is connected with pH water going in, but it is a little bit complicated. For example: you water with pHed water to 6,7 without nuts (EC 0,6). Than your soil pH is between 6,0-6,2 and it depends on how much the plant “eats”, when she eats more your soil EC is lower and pH higher and opposite way. When you provide more nuts then she can eat (but not so much to make her show you that) and performing bad watering practice, than your pH of soil is dropping down because of salt build-up and other natural proces taking place in soil. And when all of this things are taking too long than the soil pH drops down and pH of water going in losing sense because the soil changes its pH immediatelly. Thats the reason, why top growers recommend to flush soil medium at least twice during the grow, first at the beggining of flower and than in the midlle of flower. And why I wrote all of this? I wanted to explain you, that shotting your water too low is not always a good idea. I have Tap water pH 7,7, when I put nuts inside than its around 6,2-6,3 and I know I do not need to adjust it even if it is 7,0 because there are salts inside and there will be reaction in the soil and pH will be somewhere around 6,0-6,4 in case that everthing there is okay. When I go plein water, than I use drop of pH down to 10 litres of still water and pH is 6,7. You should be in range 6,2-6,8 and flush it at least once during the flowering stage to prevent built-up and lockout. Good luck

Thank you for this very useful information, it will go a long way. What are your thoughts on flushing also the last 2 weeks of flower? and how much would you consider "flushing" on a 15g pot

Flushing at itself is quite complicated thing also. If you mean flushing before harvest to “improve” the taste and lower the harsh...? It depends on a lot of factors. If you are advanced in feeding plants and provide them heavy food during the flowering, than it can help. But... When you defoliated fan leaves during the flower, your buds include more sugar leaves and you can feel it more harsh. My opinion is, that flushing does not play a big role in the taste of final buds (maybe a little) but even more important for taste is right DRYING and CURING, this makes 65% of taste and smell of bud. On the other hand, in your case you have a big pot and according to the proper “flush” you should flush it with I dont know the correct amount of water but its a lot. I mean its too complicated and so...? I would say that they mean it to flush out the salts of the soil and prepare it for another feeding. There are a lot of products which flush the salts out like the real flush do but with a significant lowering of amount of water... hope you understand my english ;-)
