Blue Dream matic auto's in coco 1st grow

To start with I had 4 seeds sit in 22 degree water at around 7.3Ph and darkness for about 3 days until there were roughly 10mm tails on the seeds, unfortunately one of the seeds cracked but never formed a tail in the water. This is my first time growing they are under a 45w led lamp (measured at 42w) for the first week then they will be moved under a 600w HID in there tent. I will try to document as best I can and maybe someone will learn from any mistakes I make or help me prevent some.

So week 2 started them on nutrients now they are looking better every day sorry for the lack of pictures my phone's camera sucks so I tend to shy away from using it I am borrowing a friends camera soon so I will try and get as many pictures as I can while I have it. I noticed a slight magnesium deficiency in the plants and decided to lower the waters ph to 6.2 as 6.7 was too high and I think it was locking the roots so I flushed with freshly made water and they seemed to bounce back fairly quickly. ****Mid Week Update**** So they are starting to fill out more. im wondering what you guys think should I switch them into larger pots now or wait a few days and I'm thinking about moving them from the 45w LED to the 600w HID tomorrow or do you guys think it will be too strong for them at this stage. So since I started them on veg nutrients I actually started them the day before I updated the post but couldnt update due to time constraints and one of the plants that was slightly lighter in color has now made a recovery after about 2-3 days and although the lower leaf tips have deteriorated they seem to be almost back to there correct color entirely new pics added too and commented on the sickly plant. poor girl she just needed her nutes.

Long time since my last update probably should have updated earlier on but hey it's all good I have written everything I have done down on paper anyway all 3 plants are doing well the sickly plant didn't start pre-flowering for about 6 days after the other two Really impressed with this strain they are in the second week of flowering and look and smell amazing sorry for the poor lighting I only have a lamp to light the tent with when the lights are off for pictures ect. A word of advice to anyone growing this strain in coco the first week I used just ph'd spring water and I wish I had used a small amount of nutrients as not only did my plants suffer early due to lack of nutrients. My next grow I have blackberry kush and tangiematics from fast buds and hope to learn from my mistakes this time around after the initial problems early were rectified they seem to have bounced back also one of my plants has an 8 bladed leaf will add pictures next time around.
