Pale leaves

Good evening All,

I have several props growing under Barina lights. Most look fine but the Sugar Plum and the KY Gooseberries seem to be bleaching. I assume this is from too much light. I don't have room to move them further from the light. Could I tent them in some way? The lower shelf has a weaker light but I worry that won't be strong enough. Please advise. TY!
