Im currently growing two tomato plants with the kratky method.
I have taken an extremely relaxed approach to hydroponics so far, basically just filling the water along with some mineral (4-18-38 masterblend, 15.5-0-0 calcium nitrate, magnesium sulfate) and shrugging and hoping for the best.
Until now i was just growing lettuce so i was able to get away with that attitude but now that im attempting a longer term plant i would like to start learning and being a bit more proactive in the outcome of my plants.
im seeing decent growth but some spotting and curling on some of the leaves. What do those symptoms point to regarding the plants health and deficiencies? Keep in mind i am a beginner in terms of hydroponic knowledge and thanks in advance for the help!
