Brown spots on most leaves

longearringboy420started grow question 4y ago

Having 3 different plants (all auto) ~1month old. I water all of them with the same solution: 2ml/l CocoAB, 1/2 RO/tap water,PH ~6. PH of output water is ~6.3 One of the 2 plants has brown spots on the leaves while the others are doing fine. What is the cause of this for 1 plant?

Do these look healthy? Thoughts? I'm new to hydro/growing I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.
