Tuesday 13/6/23 Day 86 (day 40 flower) 💧Starts Autofeed at 10.00am-12.05pm, 8 runs (5,5,10,10,15,15,15,15 total 90 mins) 5 minute gaps. 12L 3 drops ph d Feed Ec=1.51 Ph=6.5/6.8 1.5L left Roughly 2.1L each. Combined runoff 1L Ec=3.2 ph=6.2💧 Increased ducting for air in. Way to hot again. 7.00pm dimmed light to 63%=150w #4 Dli=41.7 Wednesday 14/6/23 Day 87 (day 41 flower) Had slightly better luck with VPD today. Slight improvement from yesterday. Thursday 15/6/23 Day 88 (day 42 flower) VPD still went high again and there isn't anything more I can do about it. Friday 16/6/23 Day 89 (day 43 flower) 💧Starts Autofeed at 10.00am-12.05pm, 8 runs (5,5,10,10,15,15,15,15 total 90 mins) 5 minute gaps. 13L 2 drops ph d Water Ec=0.2 Ph=6.2/6.7 1.8L left Roughly 2.24L each. Combined runoff 2L Ec=2.5 ph=6.1💧 Had a better handle on VPD today, still getting very hot. Plants suffering a little from heat stress. Saturday 17/6/23 Day 90 (day 44 flower) Signs of potassium deficiency on a few. Checked ph pens, bluelab spot on, essential 0.4 below with cold water. Again better handle on VPD today even though its hot. Sunday 18/6/23 Day 91 (day 45 flower) 💧 Starts Autofeed at 10.00am-12.05pm, 8 runs (5,5,10,10,15,15,15,15 total 90 mins) 5 minute gaps. 14L 3 drops ph d Water Ec=0.2 Ph=6.2/6.2 3.1L left Roughly 2.18L each. Combined runoff 3.5L Ec=1.95 ph=6.0💧 #4 Height= 70CM Dist= 36CM DLI=41.3 Slightly better weather. Rough week really, apart from day 91 it's been so hot here it's played havoc with the grow. This is why i should have taken the scheduled break. I don't think the weather has done much damage but it can't carry on like that for much longer. I'd say this one struggled the most this week, she is slap bang in the middle of the others and is over crowded.
