First Grow - Big Bang Auto's

DEGS420 First week of first grow over. Had seeds in water for couple days then straight into 7 gallon pots. Not sure if should have gone smaller first but hoping is fine this way. Two of the four plants going strong one slightly behind them height wise and the last is bent over. Hoping now I removed the pod of this one it will start to recover. Welcome any comments or tips anyone has to improve my grow & knowledge

DEGS420 After shooting up in first week not a lot happened in second week apart from looking like they have given up. The leafs on plants seem to have curled up and don’t seem to be growing. Not sure if I should have started in smaller pots and if I have underwatered as was being careful not to over water them. If anyone has any ideas where I have gone wrong and best way to get them looking healthy be great ?

DEGS420 In the last couple days of week 3 most of the plants seem to look bit healthier and producing more leafs. Still trying to work out what went wrong but with @KaliChakra advice have increased the air temp to 25C and have reduced watering slightly. I am now giving each plant about 2.5l every 3/4 days rather than 2/3 days. Am considering turning both of the vipaspectra 900w settings of veg and bloom on but unsure if the plants are ready or is necessary yet? If anyone can spot any rookie mistakes im making or how to save plant C be much appreciated

DEGS420 Starting to show some signs of growth but still not growing up much. Have been struggling with getting watering correct seem to switch between over and under watering. Plant C still seems like mite not make it but will keep it in for now. Plant B was healthiest beginning of week but now has burn on the lower leaves not sure if is nutrient burn or deficiency of something if anyone can tell from photos be appreciated? Due to low humidity have added small humidifier to keep humidity up still not going much above 50% unsure if this slowing process down as well.

DEGS420 End of week 5 and most of the plants seem to be growing noticeably quicker than before showing signs of lots of new growth. All plant have suffered nutrients burn due to my lack of knowledge but thanks to @B4RNS for sending me over to grow boss on YouTube now have much better understanding of ppm and feeding schedules and can now say that the schedule I got offline was 3/4 times the concentration I should have used which may explain the brown dead leafs. Hoping they will recover if any one has any tips on treating nutrient burn after the fact be greatful to hear them

DEGS420 Pretty much gave up on these girls as was my first grow and killed one and other 3 looked like they were following suit. Wish kept diary going ended up with some lovely buds and good smoke recommend these seeds to newbies seem hardy
