Multi strain in coco feeding canna nutes under gavita hps

I left my brother to mist the seedlings whilst i was in amsterdam for 4 days, got back expecting growth but found the plants have stretched and looked leggy and not much growth apart from stretch…(should have took photos before repot) I planted the seedlings in clear plastic cups with holes punched into the bottom, the medium was very moist and wasn’t seeming to dry out soo i decided i would repot in red cups as i heard clear cups are bad for roots…(feed the girls very lighly was due to bad drainage more then over watering)… I used fresh coco and pulled away as much moist coco as possible without disturbing roots, i added great white to the medium and root balls of the seedlings and repotted burying the stretched stem as much as possible… I didn't water the coco prior or after the repot as i didn’t want to stress the plant further if the roots have been getting drowned by excess water in the coco due to poor drainage, i sprayed mist above all seedlings when all was transplanted very very lightly with a micro dose of rhizotonic by canna… 1 blueberry muffin seedling looks like its going to die the other 2 are okay. I have attached photos after transplant should have photographed before transplant but didn’t 😅 When should i water next seedlings are hard work i usually runs clones that come of a defent size and root structure…🤷‍♂️ My ppm is 150 tds from the tap Ec is 0.4 out the tap Im dechlorising my water with tap safe for 24 hours before use. I have been recommended to ph to 5.8 is this correct ? My temps are around 23-28 degrees And humidity around 55% - 80% Love for reading this far, i will be posting a update every week, Any help or advise would be greatly appreciated 👊❤️

Day 19… These girls had a tough start to life i think some locked out or maybe all but some strains where more resilient maybe… I stoped putting in nutes and just added cal mag to make the ec up to 0.4 and ph’d plane water at 6.2. I lightly misted the girls with a spray bottle and within 24 hours you could see the difference plants looked better colour and new growth appearing. The girls was defo stunted i hope i have sorted this problem out now 🤞 I got 10 cuttings as the girls wasnt doing to well 5 x rs11 and 5 x banana conda Will make a seperate diary for them please check them out.

Day 31 veg… Some these girls are looking mutated 🤨 I have really low humidity which i will correct with a Humidifier tomorrow… What are these mutants coming from is it heat stress ??? And also the spots on my girls ? I have been on holiday for a few days so made a pre mixed feed for the girls for my freind to water… Im not aure if the badly mutated plants are worth pulling or growing out still?? Anybody got experience with them ?? Could it be down to really low humidity Girls will be getting transplanted tomorrow.. Check my other cuttings diary Temp 25 day 19 night Humidity high 45 low 20
