Amnesia Auto & OG Kush in 2x2x4 Tent

Absolute noob here first time growing after 3 months of research. After finally germinating the seeds and planting them I suddenly realized that I didn't note anything about quantity of water when watering the plants and so I have taken a conservative approach. I feel I have drastically under watered both plants so far and I am slowly increasing the amount of water each day so as to not shock or drown them (any advice on this would be so great). I think I was meant to pre-soak the coco and perlite so that it is damp when the seeds are planted but I somehow missed this part during my research! SUMMARY: I germinated the seeds using both the submerging and paper towel methods before planting them into the coco/perlite. The Amnesia germinated in roughly 35hrs (13hrs in water/ 22hrs in paper towel) and the OG Kush took a little longer at roughly 63hrs (13hrs in water/ 50hrs in paper towel) with the Amnesia taking roughly a further 36hrs to sprout from being planted and the OG sprouting in roughly 42hrs. I started off giving each seedling roughly 60ml per day of tap water and calmag pH'd to between 5.8-6.4 and slowly increased the amount each day up to 500ml by day 3 which looking back now was more than needed. The seedlings received their first feed on day 4 when I gave them each 1L and then I continued to up the daily amount of water up to 1.5L by day 6. I figured I would use this as my detailed grow diary that way other people can see my first approach and learn from my mistakes. Detailed breakdown of 1st week below. Saturday 29/08/2020 8:30pm Seeds went into glass of tap water and went in tent, light and fans off, heat set to 22-24°C Sunday 30/08/2020 11:15am Seeds still floating but sunk to bottom of glass after a couple of firm taps. Placed seeds into moist paper towel in ziplock bag and placed in cupboard between blankets Monday 31/08/2020 01:00pm Amnesia seed has sprouted a 1cm tap root but OG Kush hasn't popped at all Monday 31/08/2020 08:30pm Amnesia seed tap root has grown to 2-3cm but still no signs of life from OG Kush seed. Possibly see the start of it opening but too hard to tell. Will give another 24hours. Paper towel still damp in ziplock bag. Tuesday 01/09/2020 08:30pm Amnesia tap root is about 6cm long and OG kush has finally popped with about 1/2 inch tap root. Tuesday 01/09/2020 08:50pm Planted both about 1/2 inch - 1inch deep and sprayed roughly half a shot glass of water and calmag (pH 6.2) over each after lightly covering with coco. Had to keep intake fan off due to positive pressure and I've also kept the oscillating fan off to help increase heat and humidity for now as my humidifier is yet to arrive [26°C/60%] Wednesday 02/09/2020 12:00pm Neither have sprouted yet. Medium very dry so gave another 50-60 squirts of water...I have no fucking clue how much water to give but have read that they are very delicate at this stage and notice people water with droppers or spray bottles so surely cant be that much water. Wednesday 02/09/2020 11:10pm Coco around seed area was still dark coloured but there just wasnt enough water in the medium, it seemed too dry and so I gently poured some more water in the seed area to make it all damp [24°C/62%] DAY 1 ------- Thursday 03/09/2020 12:00pm Amnesia has sprouted!! About 1cm tall. Still no signs of life from the OG kush but it is about 18-24 hours behind the amnesia judging by tap root growth. Coco is still damp and so I haven't watered. Will check again later tonight and give a little more water [24.5°C/64%] Thursday 03/09/2020 08:00pm OG kush has sprouted! Both were drying out so I gave another 60 squirts (1/2 shot glass) each to the area around the seedlings [24°C/60%] Both still have a little moisture about 1 knuckle deep and so I have not watered yet. The amnesia has not grown since yesterday but OG has caught up [24°C/58%] DAY 2 ------- Friday 04/09/2020 08:50pm I gave both seedlings a good amount of water each by both spraying and gently pouring water on the surrounding area. I switched the oscillating fan back on to get the air moving and encourage strong stems forming and gave at least twice as much water as previous waterings (possibly around 250ml) after reading that the top layer of coco should never go dry and dusty which it was (still slightly damp knuckle deep). The seedlings have had roughly 2 litres of water since planting. I read the less water you give encourages the roots to grow more [24°C/54%] DAY 3 ------- Saturday 05/09/2020 05:00pm Mixed nutes for week 1 though I accidentally put 0.2ml extra micro due to a misread of syringe. Actual amount is supposed to be 1.2ml per 5 litre and I put 1.4ml. I dont believe this small an error will cause problems. (pH 5.8) [26°C/50%] I will water with just water and calmag again for today and start Nutes tomorrow. It's still not quite dry 1 knuckle deep and so i will water later. Saturday 05/09/2020 09:00pm I lowered the light about 5" so it sits at 26" above the plants. I gave both plants about 500ml water each which is again about a further 50% increase from yesterday. The amnesia has not grown at all but the og has stretched ever so slightly today [22°C/53%] DAY 4 ------- Sunday 06/09/2020 09:00pm Both plants had not dried out properly, coco around seedling still darker than rest of pot and damp to touch. However as I am already concerned that I have underwatered thus far I'm leaning more toward too much water better than too little at this point plus I believe I needed to irrigate today. With that being the case, I intended to water until runoff (not much, just wanted to see some runoff to see how much water I needed to give to produce runoff) however after giving 1 litre with not a drop of runoff, I decided to leave it at 1L each for tonight [24°C/55%]. They have had their first feed of the below schedule. https://www.growweedeasy.com/wp-content/uploads/2015/06/Recirculating-Nutrient-Schedule-custom.jpg DAY 5 ------- Monday 07/09/2020 07:00pm Added a humidifier to the tent and set it at 25% power. I gave each plant 1L of water and calmag as I'm supposed to give water every other feeding. The serrated leaves have grown slightly bigger on both seedlings but no change in height. DAY 6 ------- Tuesday 08/09/2020 09:30am Good thing I checked the environment before I left for work this morning as the humidity had surpassed 75% by 01:00am and was at 85% by the time I checked at 09:30am! I turned the humidifier off completely Tuesday 08/09/2020 11:40am Humidity has now dropped to 75% but will continue to drop as the day goes on without humidifier on. Tuesday 08/09/2020 09:00pm The humidity levels remained above 70% until 04:45pm when it dropped to 69%. Temps have been VERY high today in tent with lowest being 24°C and it increased slowly all day reaching a high of 30°C by 05:00pm. I fed the plants the remaining nutes I had mixed which was 1.5L each. I'm careful to not allow the liquid to touch the plant to avoid nute burn. I logged onto grow diaries after having fed the plants and found I had 2 answers to my question about how much water to give seedlings and it turns out I have been overwatering the plants...quite drastically so as well. I have been advised to just give the plants enough water to last them 24hrs, and another hero commented adding that they give 80ml per day until the plants have a few seeds. I will read up on the best corrective approach to overwatering tomorrow but I feel I might not water them again for at least 48 hours now and hopefully they will have drank all the water up in that time. I have switched the humidifier back on its lowest setting for overnight, hopefully this will maintain around 70-75% RH [25.5°C/75%] DAY 7 ------- Wednesday 09/09/2020 No water or feed today...they both look fine and healthy [24°C/63%]
