So just finished week 4 and the plants are starting to smell and appear to be going into preflower. Overall so far so good I think. My questions are:

Is my light too close? I have now cranked it up about halfway. Don’t want to over light or under light. Also, with nutrients, despite the PH balanced water, how much do I really have to add? The only ones I have on hand are FloraNova Grow 7–4-10 and FloraNova Bloom 4-8-7 as recommended at hydro store. Thanks so much from this first time grower.

Looks to me like your plants kinda like the light the way it is. Raising it would make them stretch a little which really would not be a bad thing.

Wanted to add that one of my plants has 3 leaves that look like this. Deficiency? Mag? Cal? Phos? Than k you.
