Auto blueberry 00seeds

Week 4 and these girls are looking great the cheese is looking as though it's a week behind the bubblegum but still looking nice and healthy and I was expecting it to be slower as it has a longer flower time. My 2 bubblegum are growing really well pheno number 2 is by far the biggest even after I snapped a branch completely off. I've noticed an uptake in water I'm now giving them 2 litre of 6.5 ph plain water every other day. Theres a slight hint of candy as you enter the grow tent makes my mouth water every time I walk in. The LST has gone well (baring the one snapped branch) all bud sites are exposed/tied out towards the exterior of the pot, looking forward to watching them develop and I will be keeping an eye on them for signs of pre flower as the bubblegum is supposed to be 8 weeks or less. Day 31 I think pheno 2 is in early pre flower stage, she is consuming 1.5 litres of water every day and is growing at a great rate. Pheno one is a little smaller and has no signs of flower as of yet, she has had the same feeding and watering as pheno 2 Cheese critical I think is looking good but I'm not seeing much growth I'm wondering if she may be stunted I'm going to check the ppm run off and see if theres any indication as to what's going on That's all for now guys and gals happy growing
