Bubbas Gift Autopots

Really happy with canopy at this point and time to switch to flower .. I'm excited!! Completed 36hrs of darkness before the switch to 12/12 I added 2 Mars Hydro ts600 hoping for more dense nugs ... End of week 5 (1st of flower) noticed leaves on the plant getting alittle brown around the edges looking like nut burn .. so like I mentioned before it's my 1st time using the autopots ... I noticed in the resivor when the level was low , I have a small pump circulating the water .. its was really bubbling . Almost looked like water and soap ... never seen this happen before, maybe to much power on the pump?? Also I'm using advanced nutrients ph perfect When I 1st check the ph which I hardly never do with advanced nutrients it was 6.8, when I noticed the issue the ph spiked to 8 in the resivor... when I looked in the autopots the water solution was very clumpy and nasty ... Let's just says the plants are not happy at all.. They went from beautiful to shriveled up in 12hrs while lights were off .. if anyone ever had this issues I would love some feed back... I might also shoot advanced nutrients an email see what's up So my chilling saturday became some work .. (im not complaining 🤣) Emptied the resivor gave it a wash , mixed up 21L with 35ml of advanced nutrients flawless finish.The ph after only using flawless was at 7.5, I brought it down to 5.8 with white vinegar Disconnected the autopots and emptied /washed the trays and floats. Placed the pots in a Home dep bucket and manually flushed until runoff filled half HD bucket ... Will run only water with flawless ph @ 6 until plants bounce back .. fingers crossed I'm using almost every advance nutrients product and flowing the chart but using 3/4of recommended dose .my TDS was 1000-1100. will cut that back to to 40% ..
