Added KMPS once a day to the Reservoir to reach ~450 mV ORP. Added Yara Kristalon Blue and Calcinit 1:1, no ml values, used the fertilizer to reach stated EC values. PH correction with Phosphoric Acid. Some roots are showing but hard to see on pictures due to my bad endoscopic camera. PPFD 300, DLI 19 Values are average of the day.

Pictures are taken at the end of the week. Did not add KMPS for 2 days in the end, will begin again next week. Added Universol Yellow (High P) and Calcinit 1:1 to increase EC and root growth, no ml values, used the fertilizer to reach stated EC values. Roots are now clearly visible, turned of the sprayers for photos. Changed light hanging height to 50cm and intensity to 50% midweek. Turned off the exhaust at night to increase RH and Temp, at this stage this is great, later not so much. The Plant is kinda slow growing on top but roots are doing good she will probably accelerate top growths soon. Values are average of the day.

Added Universol Yellow (High P) and Calcinit 1:1 to increase EC and root growth, no ml values, used the fertilizer to reach stated EC values. In addition to KMPS I added POLY(DIMETHYLAMINE-CO-EPICHLOROHYDRIN) in a very small dosage to the tank, this helps to keep the ORP stable high, did that on the last day of week 3 so results will be visible next week but it already did and the last hours of week 3. The plant is still slow growing on top, but roots are doing well. She is a girl that is visible now but really early. I don't know what is going on because there are no deficiencies, roots are healthy, etc. the other plant in the same system is growing vigorously. Did top her anyway. Removed some leafs that were blocking new nodes. Values are average of the day.

I raised the EC to ~2000, lowered ORP to ~100 and didn't see any tip burn yet, will observe the plant and might increase it even more, haven't grown this strain yet. No smell yet. Roots are looking good, maybe a little stained due to Universol Yellow which has a strong yellow color. Did more LST and defoliation, with the stretch I might reach the frame for Scrog next week? So I noticed a mutation that has been there for a while but I only noticed it this week, this plant is giving me a little headache with the slow growths on top and mutations but mid week it started to grow more, maybe it is coming back right now since the roots are doing good from start and the plant laid a good foundation before it takes off now? I had worse starts with great results. Since stretch definitely started mid week and flowering is starting I will count it as flower mid week but will mark is as flower on GD starting next week. Also added predator mite pouches as precaution, better safe than sorry. Values are average of the day.

Noticed some slight Nitrogen deficiency so I removed 20l of the tank and added 20l with Yara Kristalon Blue 19-6-20 + Calcinit A+B and it seemed to do the trick. Went low on ORP this week. Saw slight tip burn so I'll lower EC next week seems that ~2000 is the sweet spot. Did some defoliation as usual whenever needed, never noticed any stunting in any timelapse, also did a little lolipoping. She definitely came back on top after laying a good foundation with the roots growths. Canopy could be more even and she isn't spreading out properly but it is OK. Values are average of the day.

Added Yara Kristalon Orange, Yara Calcinit and a little bit of Haifa GrowClean to the reservoir. Adjusted PH/ORP, PH- adds P and ORP adjustment adds K. Light intensity is measured at the hottest spot. The stem is swelling, the netcups are 24/7 soaked due to the pipe being full with roots and increased water levels, next grow I'll go for a bigger pipe. The stem is not getting soft it is actually harder at the splitting part. Flowers are beginning to form more and more, no deficiencies, stretch stopped, EC 1800-2000 seems to be a good range for this strain/pheno in my specific setup. Did some defoliation as needed. Can't increase the light distance anymore, kinda hot for the super stretched branches but great for the rest, the super stretched branches don't show any sign of stress so I take that :) Nothing else to report.

Removed 20l from the reservoir and filled it up with fresh nutrients. Added Yara Kristalon Orange, Yara Calcinit and a little bit of Haifa GrowClean to the reservoir. Adjusted PH/ORP, PH- adds P and ORP adjustment adds K. Topped it up with tap water every second day, the dehumidifier pulls ~12l/day, most of it should be from the plants I've got in my tent.

Added a photo of the whole tent including both plants from both diaries, next diary will most likely be a 1 tent 1 plant. Buds are swelling slightly but still airy and not dense. Leafs are bleaching more, next week I'll do a complete refill of the tank and will be going a little easier on the KMPS because it adds to much K. Had some trouble with a minor leak through the top of the tube because it was filled to the rim due to a lot of roots and really long netcups which block the tube, next tome netcups which are not as long and rather wider instead because the current ones are choking the stem which IMO is a good and bad thing, it stresses the plant so it produes more but also chokes it a little and the stem rips at the base but it heals.

Added a photo to show where I take RH/Temp measurements from in the tent, pretty much inside the canopy. Went lower on EC this week to give the plant a little time to regenerate and pack some more before harvest. The dehumidifier is pulling less and less moisture out of the air every day, this is a additional sign to me that the plant is nearing its end. Not quite sure when to harvest, maybe next week or the week after, the plant isn't really stacking, it is frosty but I am missing the quantity, the pictures are kinda deceiving. Values are average of the day.

Added some Universol Yellow to counterpart the KMPS which has high K. ORP dropped a lot, countered it with KMPS and POLY(DIMETHYLAMINE-CO-EPICHLOROHYDRIN). RH and am ambient temperature are lower at the end of the week due to my other plant being chopped and I want a cooler climate for slow cure over 14-21 days for that one, both grow and dry tent are in the same room. The Buds are more dense than previous weeks, the supplemented K seems to do the trick and of course because it is end of life. Will harvest early next year, wanted to do it on the last day of week 12 but I was sick and holidays. Internodal spacing is good, long buds at the top. Buds smell like sweet candy with a touch menthol, lets see if that stays after cure. My mind changed about the plant in the last week, maybe this one shows just at the end. Values are average of the day.

Nothing much to report this short week (5 Days) the plant is chopped, check harvest. Values are average of the day.

Harvest day was 89. Short: Frosty plant, density is lacking, lots of leafs, some mutation, slow growing but big in the end, smells good skunky fruity for now, will update after cure. I have to compare this one to my other plant the Ultra G13 and Brain Freeze lacks a lot. It grows kinda slow, buds are not nearly as dense, trimming was horrible, overall I would say 50/50 fluffy/dense compared to the Ultra G13 85% dense and 15% kinda but not really fluffy in the same system under the same conditions. Total wet yield is just fine, can't say anything bad about that, this is limited by my tent, would have gotten more with this plant as a solo one in the 2x4. Managed to get the Net Cup out of the tube compared to the Ultra G13 which I had to saw of. Overall I would say a plant one can do but nothing to chase for, might update that after cure who knows. Update: dried weight is 280g total, 50/50 dense and fluffy buds but all are frosty, smells like sweet candy, overall a great yield that I did not expect, was kinda stressed with this one since it only came to its potential in the last few weeks but it did came. Will not grow it again in the near future but maybe some time later. Did bake some brownies with it but didn't count how much so I did not add that to the total yield.
