Stan, While changing and adjusting PH today, I noticed some slight yellowing of the tips on the largest tomato plant (see pics). I’ve been checking PH every other day and notice it creeps up to as much as 6.5 and once 6.7 (I always adjust to 5.9 to 6.0),
nutrient started at 50%. I’m going to start checking and tracking PH daily. I’ve not been checking the nutrient level since I have no means to. Your thoughts on a TDS meter – do you use one? Or is it better to simply “flush” the bucket contents weekly or some other interval? Just an FYI – largest plant is just over 7”, shortest 5” – and I’ve added a pic of the entire bucket, lastly - timing cycle remains 15 min off / 5 to 7 sec on during day. Thanks!
