Can anybody tell me whats going on here please. First time grower and i have 4 plants growing in soil under 600watt light in a 5x5 tent. Light is at 3ft above and temp is 25c, RH is 40%. Is this stress? I did some topping about a week ago. Nutes are half strenght, other 3 plants are doing fine just this one is curling and had bumps on some leafs.
