Nyc auto first ever grow

Week 7 I forgot to water them yesterday and now I'm changing it up to every 2 days as they needed about 4ltrs today to get some run off. 1st Introduced ok top up at half strength and then diluted down a small amount as I forgot to drop the doses down as I can see nute burn from the last feed. 4/2 Watered today they needed 5 and a half ltrs each. After doing some lst I realised my tent is too small so I'm going to upgrade to a new one tomorrow I hope. Will feed again in a couple of days and hopefully have the new tent set up The one that nearly died thrived and is tallest out of all 3. Amazing results I have high hopes for a decent 2-3 oz yield. 3rd the strugglers doing great she's thriving however not sure why her leaves are curling a little I just fed them like a day or two ago about 4 ltrs each?? Watered on the 6th plants looking great but they're growing together so I bought a new tent to help keep them apart. Week 8 starts on the 8th
