Im growing 7 plants from seed in rockwool with a drip system. My plants are 2.5 weeks old. I was using an inaccurate ph tester and my ph was way too high for the first 10 days or so and this has caused a whitening of new leaves and new growth is yellow. I think iv identified this as iron deficiency. How do i go about solving this problem? Any help or advice appreciated, sorry no pics today hopefully tomorrow
