Howdy everybody. First thread on here. I will try to keep it simple and quick.
5g gator aide cooler res (4g water level)
Remo nutrients supercharged kit ( Flower Week 4 basic feed schedule ) (First time running remo, usually using H.s.)
GH PH up/down
Distilled water store bought ( natural ph 5.7/5.8 very consistant ) ( have been using this since seedling ) ( ph test control sample )
Great white bennies
Led mars hydro tsw2000, 3x3 home
water temp 62-66
72-75 temps by day
68-73 temps by night
30-40% Hum day or night
(using a govee for data logging)
My plant has been amazing and stable the first half of its grow. As soon as I switched to flower (autoflower, nute change only ), and the nutes changed I am now struggling with massive PH swings. my roots are doing great, no smell, no twisting. The first three weeks of flower the ph had been rising. It would jump from 5.8 to around 6.6 every day while drinking half a gallon of water and ppms remaining 510 520. I figured it was because i had been dumping the clean water through the clay pebble medium (which i only started doing about two weeks ago because scrog is now preventing me from moving the plant everytime the res needs somthing)
so what did I do, a res drain. wiped it down on the inside with some 3% peroxide on a paper towel, while the plant sat in about an inch of clean water. I made the new soup fresh batch. before PH adjustments this soup comes out at 4.6/4.8 using distilled water AND great white. Now here is where things are getting wierd. The fresh res takes me 2ML of ph up to get me to 5.7. This was normal. It held its ph for about 8 hours, than it began to rip lower. I checked it that night and it was 4.9. here we go. I put .02 PH up in and got not a damn thing. usually this will bump my light 5g res .05-.08 ph. I turn the pump on and circulate for a few mins when adding anything. so now i add .05 ml. and i only get a ph of around 5.1/5.2.. long story short it was taking me 1 full ML to bump .1 ph upward. This is alot for me knowing that it takes me 2ML to bump from around 4.8 to 5.7. ( during veg 1ML ph up/down = 1.0 PH was how my soup reacted. ) so its needing alot of ph solution to budge the numbers.
Thats cool, fine, a little ph wander never hurt me. my problem now is, my ph is dropping from 5.7 to 4.6 every 3/4 hours. what the hell could be pulling it down that fast. could it have possibly been left over peroxide residue in the res from when i wiped it down? Water consumption is up now to a little over a half gallon a day. I began to allow the ppms to drop during the week and just add clean water along with needed amount of great white. PPm is now 150. I dont think the nutes were my issue. My tips are beginning to lightly burn for the first time in the plants life. Satellite leaves want to close up.
now before i get the whole distilled water lecture. please understand, a mounted RO filter setup is not an option where I am living. Tap water here is very stubbornly ph'd at 7 with a stabilizer and its strong. I have tried fighting it and its not even worth using, also high chlorine. The RO water available in the store near me is not clean. period. I can put a light on it and see a raindbow layer floating around the top, aswell as a pungent smell. (too many people are flushing pills) This also has a ph stablizer but a bit lower at around 6.7 which can be adjusted but its much easier to use distilled which is already at a consistant ph of 5.7/5.8 from different stores. also no rainbow layer or wierd smell. I have ran distilled for almost 1.5 year, no issues. first time running remo nutes though.
Thanks for the read, replies appreciated.
