1st DWC - Original Amnesia

Hello and Welcome, 1st Time diary and DWC, Very limited grow space sadly but it's all I can do due to my circumstances. I'm using dry nutrients produced by a local company, my ml/L is an approximate, I'm mixing at 50% NPK , 20% MgSO4, 25% Calcium Nitrate and 5% is ignored giving a dose of 1/4 strength Pro Silica for seedlings.

Start of Week 2; *Moved pot into DWC bucket. *Dropped light down to about 10 inches. *Mistakes while mixing nutrients, ended up at around 300ppm. *Daily adjustment to pH, can't locally source pH down so using citric acid which is to weak to remain stable for long. *Dropped res water level to about an inch below the net pot. Seems to be growing well, little bit slower then id like, I think it maybe due to Rockwool being a little bit over saturated, I've only watered once from the bottom at the start of the week. So I dropped the res level to about an inch below the pot, it was about 1/4 inch below the pot, I have an inch of hydroton below the rockwool and it's not suppose to wick I thought so might be this girl just isn't drinking much.

Start of Week 3; *Did 2 x Bucket changes due to Citric acid, now using phosphoric acid pH is much more stable and bucket is staying clean. *Dropped light down to about 9 inches. *Nutrients are at 200 ppm, she shows no signs of needing any more at the moment. She is growing like a weed now, roots have made it out of the pot, Very easy plant considering that rockwool staying way to moist and massive pH swings from citric acid being used to pH down. She went though 2 bucket changes because on some funky foam from the citric acid, pH is much more stable now and the bucket is staying clean since switching to phosphoric acid. 4th set of true leave is forming, hopefully we'll see the 5th set by start of Week 4 and I can look to top her.

Week 4, about Day 25 from seed; *Complete res change, PPM increased to 600 *Lowered light a little, to about 20 cm *Topped about 5 days ago *Added a few 80mm PC fans for air circulation Been a busy week, sorry for the delay this week, i've been looking at buying a house. Topped this girl about 5 days ago, she looked a little sad for about 12 hours then bounced back. I noticed a little nitrogen deficiency a few days after topping and realised she had used up all her nutrients! I added about 300 PPM of nutrients to the res so she didn't go hugry until I had the time to do the res change, which i then did today. You can see the roots have developed quite a lot over the past week, the tops and branches seem to be coming along nicely.

Week 5, she is 31 days old today; *Res changed, at 800 ppm. *Super cropped both main colas. *Installed Scrog screen. Exciting week for her, she has had some good growth this week and her scrog screen installed. There is a little bit of dark green spotting on the tips of a few older leaves, I'll have to diagnose whats going on there. Will be topped 1 more time after those tops have grown a bit bigger, allowed to recover and then I'll be switching her to flower once i see her growing again.
