1st Time Grower, DWC

They are still not too happy with me... Not liking the nutrient strength I choose again.. So after 24hrs of just ph water and 1/4 strength hydroguard. No change I thought they would appreciate just water and a root stimulate. But no change in root or plant mass. Looking like they are very stunted from nutrient burn. So moving forward I went with same strength as the 1st feeding that they liked. But I did it in a hurry before work and realized after the fact that I put that same amount I put before but didn't account for lowering the water level to 3.5 gal from 4gal. So end up being slightly stronger then before. I did add 0.5ml of hydroguard to each bucket. Also added 0.5 of bud candy to each bucket. But hoping they work with me fingers crossed. 4/12/2023 5.8/72°F/221(Left rear) 5.8/72°F/227(Middle front) 5.8/72°F/214(right rear) No sign of transitioning to flower yet. 4/14/23 Colorado Cookies recovered and jumped like a inch looking alot better! Overall Height 3.5" And I noticed that there was some growth in the root zone. But noticed there is something going on with the upper leafs. Runtz Seems to be recovering but still a little rough. Overall Height 2" But I did notice the roots mass did not change and they still appear to have the brown tint and seems to have gotten slightly worse toward the bottom of 6"net basket. I believe that's contributing to the slow recovery. Still looking alot better tho. Banana Purple Punch seems to have bearly changed at all. There's very slight growth in center. No change to root mass at all. Overall Height 1.5" Found some very helpful information on measuring EC instead of ppm and how to monitor EC and Ph. So will be doing this moving forward. I'm going to redo Banana's bucket to exactly what I gave the 1st time she was happy but this time accounting for the .5 gal change in water level. I'm also looking into if I can use the hydroguard at full strength on nutrient burned autos since its not a nutrient for the plant. But I need to fight the brown roots in runtz tonight. See if I can't get all three happy! And save this grow to a more acceptable outcome. Stats 4/14/2023 6.25Ph/72°F/222ppm(runtz) 6.33Ph/72°F/218ppm(banana) 6.28Ph/72°F/215ppm Cookies I added 1ml total hydroguard to all and added .05 total calmag to all and ph to 5.8 4/15 I changed the water on all buckets. raised the water level back to 4 gal on Banana since it has the smallest root mass. And put full strength hydroguard and full strength rapid start in all buckets amd ph to 5.8 and left it for 24 hrs. I made a floral spray of armor si at 0.33ml to full spray bottle. Wet em down good. Twice today. 4/16 I noticed Banana's leaf tips began to droup a little. So lowered water back to 3.5 gal and mixed the nutrients for 3 gal to be safe and leave ppm for cal mag and bud candy without nutrient burn. Added 0.5 cal mag and 0.5 bud candy. I trimmed all the burned leaf tips off, so I can see if and when it burns again. And since it was the best my test has looked yet I took a video and some pictures. But still need to figure out whats going on with Colorado cookies. Has spotty yellowing. Thought maybe light burn. So checked and raised like a inch or so. But there leafs below that are almost fully yellow. Like nutrient deficiency. Trying to read her but not getting it yet. gavw them a spray of armor si. 4/17 ph to 5.8 bucket stats. Sprayed with armor si 6.1/74°F/200ppm/425uscm/0.85EC(Runtz) 6.3/72°F/207ppm/440uscm/0.88EC(Banana) 6.0/74°F/210ppm/446uscm/0.89EC(cookies) Thinking about LST cookies and pull top down. But want to address the yellowing 1st. 4/18 I changed the water in buckets to just water with 50ml hydrogen peroxide 3% to 3.5 gal water and left it for 3 hrs. During this 3 hrs I turned both fans off and made a foliar spray with 0.30 ml gh flora trio and 0.25 cal mag and sprayed them down and turned the light off for 3 hrs. So after the 3 hrs peroxide treatment. I changed water out with fresh water and did my nutrient differently. I got the EC of my tap water whixh was between 0.19 and 0.23 between the buckets. Then I added cal mag to 0.5EC And added nutrients base and additions to a EC of 1.0. Then I added 4ml hydroguard to 3.5gal. And ph to 5.8 Banana 0.19EC 3.5ml cal mag 3ml GH Flora Trio 1.5ml Bud Candy 1.5ml Rapid Start 0.25ml GH Flora Macro 4ml Hydroguard 7.4ph 242ppm 517uscm 1.0 EC Cookies 0.23 EC 3.1ml cal mag 3.1ml GH Flora Trio 1.5ml Bud Candy 1.5ml Rapid Start 0.40ml GH Flora Macro 0.42ml GH Flora Gro 0.25ml GH Bloom 4ml Hydroguard Ph 7.3 235ppm 500uscm 1.0EC Runtz 0.22EC 3.2ml Cal mag 3ml GH Flora Trio 1.5ml Bud Candy 1.5ml Rapid Start 0.25ml GH Flora Macro 0.40ml GH Flora Gro 0.25ml GH Flora Bloom 4ml Hydroguard 7.4ph 235ppm 500uscm Ph all to 5.8 That was last night at 11:30pm This morning at 5:20am stats 4/19/2023 5.9/74°F/238ppm/506uscm/1.0 EC(Runtz) 5.9/73°F/232ppm/493uscm/0.98 EC(Banana) 6.0/74°F/232ppm/493uscm/0.98EC(Cookies) Ph To 5.8
